If you're looking for a Dungeon Crawler VR game, you've got several high quality options. Vanishing Realms, The Mage's Tale and Karnage Chronicles immediately come to mind. Another possible contender could be Raiders of Erda by Cooperative Innovations. The key advantage that Raiders of Erda has going for it, is the fact that Cooperative Innovations worked long and hard to try to get the combat right, and also deliver solid A.I. for the enemies that you'll be battling. As with Vanishing Realms, there is something special about walking down a dark, dank, dungeon hallway, holding a sword in one hand and a shield in the other. Raiders of Erda is another game that will try to transport you to a fantasy world of enchantment and danger.
