Humble bundle weekly is pretty good if you don't already own most of these games. I suspect many forum goers will. It's a sega pack, has company of heroes and Rome: total war plus a few more for $1. Pay $6 to get additional games, including a sega genesis pack and medival total war. Spend $15 to get total war shogun 2. I've got over half the games in the pack so not that appealing.
Steam is also running some big weekend sales, tons of kalypso games on sale (tropico!) and rockstar packs like max payne 3 and all dlc 80% off, gta 4 sale and many more.
