What video game or rather video game series do you think attracts the worst kinds of people ?
Call of Duty ? MOBA games such as LoL and Dota ? Some obscure wapanese games ?
In my opinion Kingdom Hearts has currently the worst fanbase, and I was a huge fan of the original game. It since then expanded to cater to what seem to be overweight yaoi loving hambeasts and complete manchildren. I can't even talk about how maybe Kingdom Hearts should try and return to it's roots a bit more without the forced overly "animeh" aspects to it without getting some weirdos angry.
PS: Obviously not all of fans of a certain series are bad, that's absurd, but this just outlines certain immediate impressions you get.
