How do I get cool games on my ipod touch?

[slice2020]

I have an ipod touch 2nd gen, and I want to get some cool games, or need to know what are the really good apps. I dont really want to jail break my ipod, unless its really easy, and fast, and I know the risks of jail breaking. One game I would really like to have is super mario 64, but I dont think thats possible. Thanks!
