i'm sure it depends on the tablets... for the tablets that are legitimately tablets, like ipads and kindles and stuff like that, i'm not too sure. There are probably apps you can buy that are mmorpgs ...
Then there are the tablets like the new surfaces, that are meant to basically replace a laptop, those you could probably just download a game and make it work. you may have to get a mouse or something depending on the game, I dunno how a touchscreen would affect the gameplay...
if you have games in mind I would just look it up, same thong for if you have a specific tablet in mind.
