I haven't actually played that many Mario universe games. Let's see...
M&L:SS
M&L:BiS
Paper Mario
Luigi's Mansion 2
Mario Kart DS (only Mario Kart game I played, but it's one of the few games that has stayed fun enough for me to beat all the difficulties)
New Super Mario Bros.
Wario Land 3
WarioWare: Touched!
Not quite 10 but oh well. And they're not in any particular order. I think all of them (except for Luigi's Mansion 2) are actually the only one's I've ever finished. I enjoyed all of them though, so they do deserve to be up here and aren't just because they're all I could think of.
(By the way, I have played M&L:PiT but never managed to get past the spaceship minigame near the end of the game. I should try it again. But simply the frustration from that means it doesn't really deserve a spot on the list.)
I also really want to play Super Mario Sunshine sometime. I don't know why but it just seems really cool.
