I like single player games too and I don't like multiplayer games because they are multiplayer and usually the communities there are garbage which destroys any casual enjoyment of the games
When multiplayer, then mostly with friends or brother in my case. I do love multiplayer, especially coop.
Not a fan of playing with random people though. Those PVP games aren't really my taste- and yeah; many people don't know how to play, that is, they yell, they cheat etc. etc..
