Violent games don't cut it

[ComradeMeow]

I play competitive TF2.

*puts on hipster glasses*

But seriously though, I think you're overgeneralising. FPS have become really popular in the last few years, but some of them are really not just about "mindless violence" and "slaughtering hordes of enemies". Maybe I'm a bit biased, but games like TF2 or CS:GO seem to me more about communication and strategy than anything else.

Also, MOBAs are way bigger than FPSs right now. Just look at twitch's front page. But I really find them boring lol

I understand what you mean by this but I strongly dislike multiplayer games, especially competitive ones. I find no fun in competition at all. Even playing a simple game of Battlefield annoys me because I find no motivation to be involved in the game, I would rather just explore the maps a bit and mess around then take part in the action. 

Also MOBAs are primarily a PC phenomena and their sales aren't that high as a genre. Look at VGChartz statistics and see for yourself.
