No, I think they are pretty awesome. I don't really mind if it is anime, or cartoon, or realistic. I like to see how creative they were made, and little bugs. Although some anime based games do suck, some are great.
I realy like most of them, but some I a big pice of crap... one Exemple, there's a game based on the anime serie "Gundam" that was fail, I don't know the name, but was some kinda of Age Of Empires futuristic, with graphics worst than Tibia
