I don't know if anyone uses Steam or not, but they've had a holiday sale going on for a while now. As part of the sale, they have daily deals (they change at 12 noon EST each day) that include some gems.
Unfortunately, I didn't know about the sale until the 22nd or so, so I may have missed out on some good stuff.
So far, I've bought Evil Genius for $1.99, Jade Empire Special Edition for $3.79, and Mass Effect for $4.99. (The latter two have been daily deals, and Mass Effect is part of today's deal - it was $19.99 before)
They're not part of the daily deals, but they also have both Freedom Force games dirt cheap if anyone needs them (or new copies), and Champions Online is only $10.19 and apparently includes the Steam pre-order bonus items according to what people have told me in-game.
So if anyone uses Steam or has thought about it, take a look. Hope you find something good, if you do.
Gog.com is also having a holiday sale, if you like older games. Might and Magic, the earlier Fallout games, HOMM III, and the Earthworm Jim games are just a few available for just a few bucks.
Oh man, steam and their sales are driving me crazy. I have just spent WAY too much money buying games.
I've got 36 games now.....
