I had this service for a little while last year but I decided to play around with it again and I'm finding it kind of fun. I've been playing the Sam & Max point & click games and I found this really excellent game called "Total Overdose" which is like a combination of Max Payne and Grand Theft Auto.
I really don't touch the arcade classics all that much (they'll always be more fun on the cab) but the old console and computer classics are quite entertaining when I'm bored.
Just wanted to see if anyone else uses it and can suggest anything good.
