I was very disappointed in Monopoly. It was quite a while ago that I played it, but at the place I was, it was the machine that was in best condition (some were really beat), but it got only 2 sets of quarters before I went to play something better. I don't really remember what I hated about it so much, but I remember not liking it at all.

NASCAR is not bad, and it's fun to play, but it really doesn't feel very Lawlory (heck, I didn't know it was a Lawlor design until I checked now! Usually you can just look at the PF and it's obvious). Again, not a bad pin, certainly a pin that i'd feed if I came across a decent one on location, but it's not a standout machine IMO.

Havn't played RCT.

I guess FG/Shreck is more expensive? (too lazy to check). That one is pretty good, and has a lot of Lawlor trademarks - important upper flipper, his classic ramps, mini PF, and half of the PF full of stuff. Unfortunately, you get the choice between either a corny theme, or a crude theme - the theme alone is enough to dissuade me from ever considering owning this one. Also, it's got that save-post in the middle, which makes it kinda easy at times - but that can be disabled if you own the machine (I'm going to guess that he designed a game of TZ difficulty, and then management said it was too hard).

RBION is a good one. Been a while since I played it, but I remember it being a fun game, and I didn't have to read the credits to know who designed it. I would recommend this one.
