Thief series - always fascinated me; wish I hadn't missed it
Ultima series - that would make a friend's day
Deus Ex - my fellow GOGers have nudged me toward it with fanatical praise
Homeworld - heard it's a great space game and I don't play enough of those :P
Bard's Tale - read good things about it and it seems totally worth trying

And I agree with Roman5: A working and Functional Wishlist on the front of the community page

I also think every game's info page should have a link to its forum.
