Fast paced, engaging, not unfair in game play, like other games can make fails purely set up. Developer ego my friends call it. Sorta like digital playground bullying to newbies in particular. However, NOT WITH PHOTON STRIKE! it seems to be variable in wjat is to come next, i like tjat. Doesn't get stale.
Fun, Fun, Fun game! Most games i give one try! One try to convince me to keep playing. Most games disappoint but NOT PHOTON STRIKE! SO FAR SO GOOD!
