If you want a lot of games, check out the 1C complete pack over at gamersgate. 80 games for 21 dollars (and if you got in on that 15% for life discount with an IGN prime signup, its only about 18 bucks). Been up all week, so I'm guessing it'll end Sunday night, but just saw this today.
Highlights in the pack (to me) include Space Rangers 1+2 (and Reboot - great game if you've never tried it), all of the Kings bounty series, all of the Men of War series through Vietnam expansion, UFO Afterlife series, Star Wolves series, and Fantasy Wars.
A lot of stuff I'd never play as well, but heck if you're wanting a bunch of games to tide you through a slow time in releases, $0.40 per game isn't bad. If you wanted to go really cheap, and you review the games on the site you'd even get more back in bluecoins (Between 5-25 cents worth per game), but probably unnecessary at the low cost.
