Encourages Anti-Social Behavior

The game incentivizes players to lie, cheat, or backstab other players to get ahead.

Some games encourage anti-social behavior. Combat games may encourage you to kill other players in violent ways. Driving games may encourage you to drive recklessly and break the law. Other games may encourage you to lie, deceive, steal from or backstab other players to get ahead in the game. Some games may even allow or encourage some form of cheating.

Within the context of the game, these behaviors are normalized, but you still feel bad when you are on the receiving end of one of these anti-social behaviors. If you have invested time and perhaps money into a game and then lose some of that because a friend backstabs you, that's going to cause some unwanted bad feelings. If someone steals some of your in-game resources, that may make you angry and require you to spend more time and money earning those resources back.

For some players, being on the receiving end of one of these behaviors may make them feel a need for revenge. If the player is part of a team, they may be able to enlist their teammates to pick on a particular player in the game. This will cause a negative experience for that player and may prevent them from enjoying the game.

"Yes, but that's given with being a competitive Tank MMO."

"You can organize to make tourneys manageable. But you could also be sneaky and lie. Leaving factions is also a way to lie. Cheating has been a trouble issue since this game began."

Roblox Roblox
"Some popular games on the platform (such as Murder Mystery) do indeed encourage this sort of behaviour. There are many others however that don't really fit into that category."

Coin Master Coin Master
"You can attack other players and steal from them."

"Because of the way the payout work for top ranks in the leaderboards there is an incentive to make alliances and deals with people to ensure your rank. People outside of the alliance are unfairly targeted. It's possible to snipe people at their payout time by waiting to attack them until right at the end. This isn't very fair."
