They only make games for their own consoles, you can't play their games on other plataforms. When the other consoles have like 4-5 strong exclusive titles, they have 100000 exclusive games. And, at least for me. Most of them doesn't suit my tastes. I'm not going to buy a 3DS just for one game. Sure, they have some great exclusive games, but you can't be like that at this moment. If you want to sell something, you need to work with more companies.
