I seem to remember reading a gameroom magazine interview with Pat Lawlor in which he said he delivered the whitewood and the basic rules layout, and then Stern kicked his group to the curb to finish the game in-house and that was their cost saving MO for a few years when games were never "complete" (RCT, Monopoly, Wheel of Fortune).
RCT feels like a VERY incomplete game to me, and is missing all the Lawlor nuances in the code that you just know he would have meant to be there. I mean, is there a more worthless upper flipper looping shot in pinball? The modes are horribly uninspiring except for power ride and toss your cookies.

The framework was there for an awesome game, but was never completed.

As for our RCT, my wife was a troll fan when we were kids. We went through her collection of Trolls, and she picked one out to put in place of the stock troll. The new troll is bigger, and has a tongue that he spits out at you when you squeeze him. His tongue was broke though, so it just sticks out and flops around now - a neat effect. She also made a pair of swim trunks for him so he wouldn't be naked.

Once installed, we got a really neat surprise. Due to his added height, his head will thump the glass in varying strengths during his movement. The sound/feel is similar to a shaker motor. It adds a neat dimension to gameplay so I left it alone.

For the price, it can't be beat.
