I have Time Splitters 2 and Contra for the PS2. I think overall these are both excellent games for the most part.
I love TS2, but it makes me ill. I have never experienced the dizziness and nausea I am getting from TS2 before. I am 30 years old and have been a gamer since the NES came out. I even bought the set that included R.O.B. Anyway I would like to play through it, but I can't I will eventually have seizures and choke on my own vomit. So I have to get rid of it.
Contra. It is too hard to get anywhere and I am not a kid who can sit and play the game for hours on end to get past it. I have to get rid of it.
