I've been having SO much fun playing this game. The time my group played took a little getting used to as we were all more used to slower moving systems but once you get used to it it's WONDERFUL. Everything hits hard and fast(including enemies!! Watch out) and there's a lot of fun to be had with powers. Absolutely give this a shot. I'd say start up takes about 15-20 minutes and gameplay for missions about 2-3 hours.
