Summary: One star for fun is probably mean. But there is a proviso. Okay I have nothing against making sure people don't steal. (Let's face it, sadly you can see cracks for PvZ. A game I've bought umpteen people. Less than £6 in shops for your own physical copy! Yet still gets thieved. Strewth. How sad is that.) But have bought this game so my nephew could have a game to play when visiting. Then: Load. Steam. Enter number. Steam. Start up. Steam. Try to shut down. Steam.
