KOTOR: I'm on Manaan, having finished Taris, Dantooine, and Tatooine thus far.
Torchlight: I'm on level 17, but I keep going through purchased treasure maps and quests for the guy just south of town, so I've actually played a lot more than it seems like I have.
Wallace and Gromit: I've finished ep. 1 and starting on ep. 2 soon.
Aquaria: I have the first three songs and one pet, and am halfway through Mithalas City. (Incidentally, I should mention that anyone who loved games like the original Metroid and the original Legend of Zelda should really check out Aquaria! There is a demo out there.)
