Which Wii (Mario) games should it get from these?

I would like Super Mario Galaxy 2, New Super Mario Bros and Super Smash Bros Brawl I can only get 2 though. I would like brawl, but im a few years behind and i dont think alot of people still play online. Super Mario Galaxy 2 is mostly going to be one of them, but NSMB is a classic favorite. I just want your opinions.

Thanks!Which Wii (Mario) games should it get from these?

it really depends on what you want to get. You could get one that you want, and the other, you could maybe get NSMB. Good luck!Which Wii (Mario) games should it get from these?
I liked the New Super Mario Bros because of the coop play. That being said, the other 2 are still better.
