Great to hear that you were there and that you had fun! This was the pre-alpha version so some things that are not in yet. What kinds of goals would you like to see in the game? A type of leveling up system, more abilities.
I recently played Dungeon Defenders 2 at nycc, It was a fun experience. I used the Apprentice Class :apprentice: which was the ranged caster. It was a fun open experience with HD graphics and about a 15-30 minute gameplay on hard mode one full round. The game was fun and action packed but needed more goals within the game. The game was fun and full of action and i can't wait to get into the beta.
