I feel like the gameplay itself fundamentally refuses to accept spiteful/selfish players and they filter themselves out within a few hours of playtime

You have to play the team game, even if you're the one. You cant outplay 4 people focusing you lol as long as youre clearly trying and not spamming everyone usually gives each other grace

Yes, many many hours. That game is also mostly positive, but the nasty players are hard to move on from haha. I still love the game overall.
