Sony Ericsson S700i

I not sure which one to get I want something that plays good games and has a good camera. The S700i well 1.3 megapixel is pretty good but I am guessing the games would be a lot better with the P900 since it is a PDA after all. Also, I heard the P900 looks really crappy but I really don't know which one to get. I really want to be able to play good long games like Risk or 2 player Chess but those are only for the PDA I am guessing. If not please tell me, because I really don't know much about that.
