I've been pretty straight-forward for a lot of things. (Oh come on, don't tell it's only now that you realize that I'm bluntly saying that I disapprove of something each time I say, "No" by itself when people are doing some sort of action)
If you want me to go into specifics...
1.) I don't like shooters, FPS, 3PS, Railgun FPS, Railgun 3PS (I have yet to see if one of these actually exists, certain stages in Shadow the Hedgehog are the closest I can think of that), Shoot n go (stuff like House of the Dead), etc.
Deal with it. There are simply some things I dislike in general, or at least, not like. Doesn't mean that this is a bad game or anything, simply not something I would buy/rent/play. Nothing personal
