I keep playing Overwatch because of its solid ranked system and mechanics. I play League for the same reason.
I play Phasmophobia, Among Us, and Project Winter because of the social element (a focus on voice chat and especially proximity voice).
I play Borderlands and Destiny because they have an engaging story to keep you coming back.
Toribash doesn't have a single one of these things. The idea behind the game is cool but whenever I play, it ends up being 3 QA games before I give up. There's no reason for me to play at all. There's no story, no social element, no (good) ranked system. I feel like there's no direction or structure at all.
I think that's why so many people quit this game.
