Awesome game. My company has been working closely with Trendy on a couple of projects. I've had a chance to play some of their games in alpha/beta. I'm a HUGE fan of this genre (mixing RPG with tower defense) and DDE executes it flawlessly. They've also been working on some really cool cross-platform tech which I think was written about on TC this morning. If you like tower defense and RPG games, you have to give DD a try.
