Maiden is the only game I brought home from a show where I had ZERO intentions of buying anything. It's a special game, esp for a pro. Shots are just a ton of fun and there are little strategy nuances, but nothing near dizzying territory like TWD or something.
Finally played TNA for the first time and the sound and light show was amazing, but the gameplay just feels like 3-4 shots over and over and over.... One game was enough, and I never do that.
