It's true, but there are just so many fps and fps-like bloody, brutal, killing games and ( unfortunately ) a lot of them sells well. Plus people who I meet daily ( and who play video games ) are talking only about these games, and fucking annoys me and makes me sad that they have no need for anything else, and that their taste narrows down to this point.
The thing that makes me a bit happier is that for example, one of my classmates has Rayman Jungle Run on his phone, plus when I had my tab and Rayman on it, many people have played with it and actually liked it.
Though for me it is inexplicable why the number of people who play platformers and games alike is relatively small compared to fps games.
