Let's see now...
Oblivion (if screwing around counts)
Morrowind (same as above)
World of Warcraft
Star Wars Galactic Battlegrounds (just waiting for things to build/research took far too long at times)
Gears of War 1 (finding games used to piss me off, I had a pretty poor internet connection at the time as well)
Team Fortress 2/CSS (waiting for games to load, though my tinme on CSS was very short lived)
All I can think of for now.
