Might and Magic: Clash of Heroes Free via Games with Gold Program

This puzzler/RPG hybrid takes the DS original and gives it a minor makeover. The game normally sells for $15, but is free for two weeks on the Xbox 360. It’s received reasonably high marks, but does seem to have a steep learning curve. At about 1 GB, you’ll need to make sure you’ve got some spare space on your storage device of choice. You can also just add it to your account via Xbox.com and it’ll be yours forever if you don’t want to fill your 360 up with downloadable fare you’ll never play.
