This comes with a word of warning. If you click on this link, you will most like spend money. It's pretty ridiculous. Green Man Gaming is currently running what it's calling a 'Top 50 Games' sale. Basically it's putting a helluva lot of games on sale, and almost all of them are excellent.
Today they're running down the list from 30-21. Almost all of these games are 75% off, and it's a little bit crazy.
- Batman: Arkham Asylum is $4.99 - Tomb Raider Game of the Year Edition is $7.49 - Fallout is $2.49 - Splinter Cell is $2.49 - Deus Ex is $1.74 (I mean come on!)
I guess what I'm saying is, this is a pretty amazing opportunity to stock up on some legitimate classic titles for a pretty low cost. Good luck!
