I really think you should get Mario Kart Wii as you obviously like racing games.

Also, Mercury Meltdown may be up your alley, since you did buy Monkey Ball. You should be able to get it really cheap, and essentially it is a tilt game, but with a mercury glob instead of a marble/ball

Other games that are really good, but I don't know if you'll like them
* Fire Emblem: Radiant Dawn - if you like strategy games, however I see none in your collection
* Mario Strikers Charged - great mario sports game. Very hard, but very fun.
* Super Paper Mario - Great platformer/RPG, but not much of an RPG. I thought it was very fun and innovating. The dialog can be long in parts, but other than that I have no complaints about it.
* Wario Land: Shake It! - 2D Platformer that you can find really cheap. It looks beautiful

i didnt buy monkey ball, i got it as a bundle from my friend. i think i will buy fire emblem since i liked path of radiance i am considering MK but i never liked how i would be 1st then drop to last cause of one item.

Name your favorite games/genres.

Get de Blob, Wario Land and Excitebots of course, as it's freaking awesome.

Also No More Heroes and Madworld, they are kinda short but so much fun. That should keep you busy until Little King's Story. And The Conduit. And Punch Out. And Muramasa. And Silent Hill. You are going to need a lot of money.

why the hell did you not listen to me in your other thread.

i said play world of goo nows, you will be happy you did!
