I like both Caspian Sea and Metro, the only one's I've played as of yet. They're great and worth the money IMO. The maps are only out for Premium members now. As for the game being fixed it has worked fine for me since mid December.
I loved it but I don't think it would hold up a second time. I was eating dinner and drinking a margarita during it and I didn't finish the food or drink by the end of the film. It seemed like it just hypnotized me. It was just a good experience that I woudn't want to sully by watching it again and finding out it's just OK.
