Civilization? I suggest just getting the newer PC versions if you really want to enjoy it. Unless you've never played it before then it might be good for practice.
More games;
TMNT - Turtles in Time
Super Ghouls and Ghosts
Sim City/Sim Ant/Sim Earth (if you like the sim games)
ShadowRun(you didn't include in your list, not sure if that was on purpose)
Uncharted Waters(same as above, I listed them before just wanna make sure you didn't forget)
Might and Magic
Mario Paint(not sure if this is possible for D/L)
AeroBiz(it's wierd, a business sim game, I loved it years ago.)
Oh and don't forget......
SHAQ FU 
If you haven't played it yet, try it, it's at least worth laughing at how horrible it is.
