"Top" is a pretty subjective description, so I'm going to go with a mix of my opinion and the 'expert' opinion--
Wii:
Guitar Hero 3 (I'd get this for 360, if you don't already have it)
Cooking Mama (Pretty fun, especially for parties. Sushi is hard as hell to make)
Metroid Prime 3 (Fun railshooter / FPS, but it definitely wasn't very impressive graphically)
Super Paper Mario (Kinda fuckin cool - ability to 'rotate' Mario into 3D to walk AROUND the pipe, rather than jump on top of it)
Super Mario Galaxy (Amusing, but just another N64 Mario World in 3D)
Super Smash Bros. Brawl (Not out, but slated for Feb. - I love the Smash Brothers series, so it's a pretty big incentive for the Wii)
Zelda Twilight Princess (Cute, novel use of Wiimote for fishing, etc. Nothing terribly special, imo)
Wii Sports (Not overrated. Very good easy fun for drunken visitors, etc)
Trauma Center (There's two out now - fake surgery. The second one has co-op surgery. They were definitely good for a few hours of fun at a time, especially if you like laughing at anime psuedo-story between operations)
Those are the best I can think of. Like I said, not terribly immersive.
DS:
Zelda: Phantom Hourglass (like I said, quite fun with stylus action. A bit kiddie and a bit dumbed down, but still fun)
Final Fantasy XII: Revenant Wings (in terms of 'platform exclusives' this one takes it. I love the FF series, and this one looks pretty fantastic, including graphically. I think about getting a DS just for this game, but I'm *NOT* a mobile gamer at all) - they're also slating III and IV re-re-releases.
Brain Age (definitely a bit hokey, but fun if you like timed math/logic puzzles.)
Dragon Quest Monsters: Joker (Kinda a Pokemon in the DQ world, pretty cool)
Star Fox Command (You said SNES, so I had to throw this one in. It'd be another space shooter if it weren't for the Star Fox influences. Good time waster)
Drawn to Life (Novel use of stylus; it's like mario, but you have to *draw* your way through the levels - tools, boxes, characters, etc..)
Not really 10 each, but those are the defining ones, imo.
Edit: and thank you for the avatar compliment; very few people recognize the most badass RPG hero in the history of RPGs, especially in his original guise - what the hell is this?
