Looking for some quick pickup games. Something interesting, that you can finish in under 30 minutes. Decent gameplay. Nothing elaborate. Something I can play at work while I'm waiting for a callback. I'm not looking for anything like Bejeweled or Solitaire, can't install RealNetworks, and I don't want it to be Flash based. (yeah, I know, I'm a picky biotch, but I hate real player and flash)
Anybody know of any good one's off the bat? Is there a web-site devoted to games like this?
