I've never heard somebody say something is too Anime.
I've definitely heard it. It all depends on what circles you're swimming in. I think for younger people (lower 30s and below) it doesn't seem like anime. It just seems like the kinds of cartoons they watched as kids or the kind of cel shaded graphics they grew up with. But for older gamers (and cartoon lovers) like myself, anime is a very specific style and many of the tropes can be off putting. I was never a fan of cel shading when it first started, though I have enjoyed many cel shaded games. I've also enjoyed many anime-looking games. But I certainly don't gravitate towards those styles personally.
