I had a Monopoly in my collection for a few months. It just didn't excite me, it's not a bad game though.
I took the game to the the UK Pinball Show in August. When it came back, I left it packed away in my garage until I eventually sold it last weekend. (I already had the buyer lined up for it in August), I just couldn't be bothered with the hassle of dragging it back into the house and setting it up again only to haul it back out again later, that's how much I enjoyed the game.
I have only played partly working games of RCT or RBION in arcades, and haven't played Nascar, so can't form a valid opinon on those games.
Emo, that's great to see you taking the time and trouble to write up rule sheets for these modern games.
