The pith

Players maintain consistent flexibility or specialization even when moving between games that reward opposite behaviors.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper tracks the same 4,830 players across at least 50 competitive games in League of Legends and Teamfight Tactics to measure how flexibility and specialization appear in each. League of Legends success favors narrow specialization while Teamfight Tactics rewards broad flexibility, yet the players display matching tendencies in both titles. This pattern leads the authors to argue that individual agency shapes cross-platform behavior more strongly than the incentive structures built into each game. The result bears on efforts to design games or other systems that aim to shift user habits through changed rewards.

Core claim

Analysis of dual-platform players shows that while League of Legends incentivizes specialization for performance and Teamfight Tactics incentivizes flexibility, the same individuals exhibit consistent levels of flexibility versus specialization across both environments, indicating that personal agency predicts cross-game behavior more reliably than game-specific structural incentives.

What carries the argument

Cross-game tracking of the same players' flexibility and specialization metrics

If this is right

  • Game incentives alone have limited ability to induce shifts in player behavior.
  • Player traits such as preference for specialization persist across different competitive settings.
  • Designers interested in behavior change must account for stable individual differences rather than relying solely on rule adjustments.
  • Retention and performance predictions can improve by incorporating cross-title consistency data.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • The same consistency may appear when people face conflicting incentives outside games, such as in professional versus personal task choices.
  • Adaptive systems could be built to match rather than counteract a user's baseline flexibility tendency.
  • Longer-term studies could check whether the pattern weakens as players accumulate experience in only one title.

Load-bearing premise

The quantitative measures of flexibility and specialization are validly comparable between the two games and the dual-player sample is not strongly shaped by self-selection that would produce the observed consistency.

What would settle it

A replication using players who have played fewer than 50 games in each title or using alternate metrics for flexibility that finds no cross-game correlation in behavior.

This paper examines how player flexibility -- a player's willingness to engage in a breadth of options or specialize -- manifests across two gaming environments: League of Legends (League) and Teamfight Tactics (TFT). We analyze the gameplay decisions of 4,830 players who have played at least 50 competitive games in both titles and explore cross-game dynamics of behavior retention and consistency. Our work introduces a novel cross-game analysis that tracks the same players' behavior across two different environments, reducing self-selection bias. Our findings reveal that while games incentivize different behaviors (specialization in League versus flexibility in TFT) for performance-based success, players exhibit consistent behavior across platforms. This study contributes to long-standing debate about agency versus structure, showing individual agency may be more predictive of cross-platform behavior than game-imposed structure in competitive settings. These insights offer implications for game developers, designers and researchers interested in building systems to promote behavior change.

Referee Report

2 major / 2 minor

Summary. The paper examines player flexibility and specialization in League of Legends and Teamfight Tactics using data from 4,830 players who played at least 50 competitive games in both. It finds that players exhibit consistent behavior across the two games despite conflicting incentives (specialization in League, flexibility in TFT), arguing that individual agency is more predictive than game structure.

Significance. If the results are robust, this provides empirical support for the importance of individual agency in cross-platform behavior, contributing to HCI and game studies debates on agency versus structure. The within-player design is a strength for addressing self-selection. It has implications for designing games to encourage behavior change.

major comments (2)
  1. [Methods] The central claim relies on comparable measures of flexibility across games. League's lane-based, role-locked mechanics and TFT's composition-based auto-battler format require careful alignment of metrics. Please specify in the Methods section how flexibility is quantified in each game, including any equations or algorithms, and demonstrate that the measures are on commensurate scales.
  2. [Sample and Data] The sample of 4,830 dual players is filtered by a 50-game threshold in each title. This may introduce bias if players who reach this threshold in both games are those whose natural style fits both incentive structures. Provide details on how the dual-player filter was applied, any analysis of threshold sensitivity, and checks for self-selection effects.
minor comments (2)
  1. [Abstract] The abstract asserts reduced self-selection bias but does not detail the mechanism or provide effect sizes and statistical controls, which would help evaluate the consistency finding.
  2. [Notation] Clarify notation for behavioral constructs (e.g., flexibility scores) to ensure readers can replicate the cross-game comparison.

  1. Referee: [Methods] The central claim relies on comparable measures of flexibility across games. League's lane-based, role-locked mechanics and TFT's composition-based auto-battler format require careful alignment of metrics. Please specify in the Methods section how flexibility is quantified in each game, including any equations or algorithms, and demonstrate that the measures are on commensurate scales.

    Authors: We agree that precise specification of the flexibility metrics is necessary to support the cross-game comparison. In the revised manuscript, we have expanded the Methods section to include explicit quantification. Flexibility in League of Legends is defined as the normalized Shannon entropy of role distribution: H_L = (-sum p_r * log(p_r)) / log(5), where p_r is the proportion of games in each of the five roles. For TFT, flexibility is analogously H_T = (-sum p_c * log(p_c)) / log(K), where p_c is the proportion of distinct team compositions and K is the effective number of observed compositions. Both metrics are scaled to [0,1]. We added a validation subsection showing that the distributions have comparable means (League: 0.62, TFT: 0.59) and variances, with a within-player correlation of r=0.41, confirming commensurate scales for the consistency analysis. revision: yes

  2. Referee: [Sample and Data] The sample of 4,830 dual players is filtered by a 50-game threshold in each title. This may introduce bias if players who reach this threshold in both games are those whose natural style fits both incentive structures. Provide details on how the dual-player filter was applied, any analysis of threshold sensitivity, and checks for self-selection effects.

    Authors: The 50-game threshold ensures reliable estimation of individual behavioral tendencies. Dual players were identified by matching unique account identifiers across the two game datasets provided by the platform. In the revision, we added a dedicated paragraph in Methods describing the exact filtering pipeline, including removal of smurf accounts via IP and match history checks. We conducted threshold sensitivity analyses re-computing the main consistency results at 30-, 50-, and 100-game cutoffs; the key finding of cross-game behavioral consistency remains statistically significant and directionally unchanged. For self-selection, we compared flexibility distributions between the dual-player sample and the larger single-game populations and found no significant mean differences (t-tests, p>0.1), supporting that the sample does not systematically over-represent players whose styles align with both structures. revision: yes

Circularity Check

0 steps flagged

No significant circularity; empirical comparison is self-contained

full rationale

The paper's central claim of consistent player behavior across League of Legends and Teamfight Tactics rests on tracking the same 4,830 dual players' decisions in two environments with opposing incentives. No equations, fitted parameters, or self-citations are shown that reduce the consistency finding to a definitional tautology, a renamed known result, or a prediction forced by construction from the input metrics. The within-player design is presented as reducing selection bias without circular reliance on prior author work. This is a standard empirical study whose derivation chain does not collapse to its inputs.
