multiplayer games need more casual gamemodes. and by that I specifically mean:
gamemodes where winning vs. losing mostly comes down to luck
gamemodes that go on forever, like 24/7 TF2 servers
gamemodes with “blue shell” mechanics that make things harder and harder for the more skilled players while making things easier for less skilled players
gamemodes where there is no concept of “winning” vs. “losing” (for example: a gamemode where you change teams each time you’re killed, and the first team to have every player on it wins)
