The roguelike nature of Rainbow Yggdrasil with its infinite play and variable rewards could lead to extended play sessions. The competitive aspect of comparing clear turns with other players might introduce social comparison. While there are no direct monetary risks, the game's design could be highly engaging and potentially lead to excessive playtime for some individuals.
