It can't be denied that Sonic has great soundtracks on its games, that's for sure.
I'd say my favorite song would be Chemical Plant, but I haven't decided for a favorite song of the series, not even soundtrack of a full game.
I loved what little I played of Super Mario RPG, but I haven't played it in about two years and i'm afraid i'll get lost if I comeback.
Happy Spooky month to you Michael.
I forgot to mention how Portal 2 felt familiar with the first game, with the first basic gunless puzzles, the return of the gun, and such. However, I can already tell that they indeed brought the production values to its maximun and it feels like it's going to be a bigger game. I can't wait to continue.
If you like games like Gauntlet or any of those hack-n-slash games, you will definitely enjoy the game. Your only limitation would be your PC....
Now I see. No one plays with the trackpad, ever! 
I did own Banjo Tooie on my original N64, but sadly because I was a five to seven year old kid that couldn't read even if his life depended on it, I never made it far and I was scared of trivial enemies or so.
I've got the first Thief, but I haven't started it.
I also need to play Majora's Mask.
I've given 3 hours to Deus Ex and completed the first mission and indeed, it's quite great if a bit dated.
Finally, I agree with THPS 2. I love the games in general and everytime I had the chance to play this one on someone's PSX (I didn't have the console) I loved exploring the maps and playing around the skate park creator.
You should play Portal. I know your disdain for mouse and keyboard controls, but they are great in Portal.
Both, single and multi.
It's also an indie and has pixel graphics.
It's an isometric action game similar to Gauntlet were you take your fantasy class character though a castle to escape, collect loot and beat bosses.
I'm thinking in re-visiting Amnesia: The Dark Descent and talk how it scares my pants.
