It's the site that keeps on giving. GOG.com has done it again by giving a free game (
Jagged Alliance: Deadly Games) to all users that had an account prior to September 20, 2010. Users will be able to login to their accounts and check their virtual game collection to download the title starting today. If it's not there yet, it will be in the next few days.
There is also a sale going on that makes Strategy First titles available
at up to 50% off. In total, it's 18 different games on sale. I actually haven't played a single title on the list so I'm unable to offer a suggestion.
Check out the sale while it lasts.
