To start with the troll: yes it's very annoying and will drive you insane!
Nascar is a great game in terms of 'things to do'. It has many different modes and is quite a challenging game altogether.
I don't really know Ripley's.
As for Monopoly, we've had one in the game room for over a year. Its a fun game, very clean design and brightly lit. It's been some years since I have played one, but from what I can remember it was fun and I played it a lot. The tiny left ramp is really fast and the little rotating flipper makes for some crazy gameplay! Have you played it recently yourself?
