Saga is an MMORTS by Silverlode Interactive, where you can command literal legions of troops in never-ending battle. While it's free-to-play, there are two versions of the account: a $19.95 commercial version, and a free, features-locked version. Well, for those of you eager to give this a shot, Saga has just teamed up with FileFront to offer 50,000 commercial accounts. At nearly $20 per account, that's close to a million dollars' worth of players!
Jaunt on over to FileFront to download the game and get your beta key. But don't forget to sign up on Saga's site for your free account first!
