Artificial Intelligence in Games

Paid 'loot boxes' are products in computer games that consumers can purchase to obtain randomised rewards [1]. Loot boxes are structurally similar to gambling [2, 3], and loot box expenditure is correlated with problem gambling severity [4, 5]. Zendle et al. [6] influentially reported that loot boxes are prevalently implemented in United Kingdom (UK) games in February 2019: specifically, inter alia, that 59.0% of the 100 highest-grossing iPhone games contained loot boxes. Xiao et al. [7] conducted a replication and found that 77.0% of a comparable sample contained loot boxes in June 2021. Overall, 76.9% of the 52 games only appearing in Xiao contained loot boxes, whereas 63.5% did in Zendle. This suggests that games with loot boxes became more popular over the intervening time period. However, there were 11 disagreements (22.9%) among the 48 overlapping titles, each of which involved only Xiao identifying loot boxes, whereas Zendle did not. Table 1 summarises each disagreement, and timestamped screenshots of loot boxes uniquely identified by Xiao are available at: https://doi.org/10.17605/OSF.IO/CX5RV. Known to have implemented loot boxes prior to Zendle's data collection through the egg incubator system, as documented by changes to the game's Fandom Wiki page dated 2016 [9] (The loot box identified by Xiao was relatively unique and similar to the implementation in Counter-Strike: Global Offensive (CS:GO) and may have been missed by Zendle: players were able to pay real-world money for incubators to act as 'keys' to unlock Pokémon eggs, which contained randomised content and were the 'loot boxes'; the eggs themselves were not directly purchasable and were obtained through gameplay. However, there is an upper limit as to how many eggs a player is allowed to have simultaneously: without purchasing incubators using real-world money, the player will quickly reach that limit and lose the opportunity to obtain more eggs and, by implication, more randomised content.) Seemingly implemented randomised mechanics through the Materials Chest system prior to Zendle's data collection, as documented by YouTube videos dated, e.g. 2017 (timestamps: 0:56 and 1:05 show that Materials Chests contain randomised content and 17:02 shows that they can be purchased with real-world money) [10] (The loot box identified by Xiao could only be purchased as part of a bigger bundle of many products and therefore was relatively hidden and may have been missed by Zendle.) Game 1 disclosed starting to sell loot boxes between the two studies [8]. Xiao also discovered relatively obscure loot boxes in four games that Zendle did not: games 2 and 3 were known to implement loot boxes during Zendle's data collection period [9, 10]; game 4 likely also did as revealed by contemporaneous evidence [11]; and game 5 potentially contains loot boxes implemented by third-parties through user-generated content. A methodological difference may have allowed for more accurate identification by Xiao: Zendle reviewed online videos recorded by other players and, if unable to decide, then through personal gameplay, whereas Xiao determined through gameplay and, if unable to decide, then through online resources. Studying video games through personal gameplay, whenever possible, is likely preferable. Further, recovering older versions of the software to verify is now likely impossible, which is why future research studying video games should account for their easily changeable nature by following open science principles [12] (e.g. through providing screenshots). Additionally, five games were simulated casino games [13], and a sixth game allowed players to virtually operate physical claw machines (which are an older quasi-gambling product available to children) [14]. These games bore near identical names alluding to gambling at both data collection points, so their primary content likely did not change. Zendle did not recognise certain simulated casino games in which players can spend real-world money to buy more stakes to continue participating in simulated gambling as loot boxes, although such randomised mechanics requiring payment to engage do fall within the definition of 'loot boxes' from a ludology perspective [15], as they similarly use gambling-like mechanisms, and are, therefore, relevant to policymaking concerned with addressing potential harms [16]. Paid loot boxes are now more commonly implemented in the highest-grossing UK iPhone games (which are reflective of other Western markets) than reported by Zendle. This is because of multiple reasons: games with loot boxes becoming more popular; some popular games subsequently introducing loot boxes; methodological factors around loot box identification; and semantic ambiguities around what constitutes a 'loot box.' Policymakers [17-19] and researchers should proceed on that updated basis. Thanks to Dr. David Zendle for making the underlying data to Zendle et al.
