Dungeon Defenders

Had some friends tell me about this downloadable PS3/XBox game on my trip and just got it myself a couple of days ago. It is a really fun tower defense hybrid game. It sorta reminds me of Orcs Must Die, but it has more RPG elements than that game. Dungeon Defenders has a nice weapon/gear/pet system. You can also upgrade your gear. You can have multiple heroes, and can even swap them out between waves, so your hero with a strong tower build can put up your defenses, then you can switch to a strong offensive hero during the waves.

Pretty sweet little game overall, I highly recommend it.
