WPT at 187 is a hell of a lot of game. I love the deep code and the different layout. Super challenging. I'd definitely buy one for home use.
Big Hurt is a fun game too, especially for a Gottlieb, at 248. Probably my favorite Gottlieb game. I loved playing it on route back in the day and blowing that game up. It's a lot of fun hitting home runs, grand slams and collecting cards.
I've always liked Wrestlemania which comes it at 230. The theme took people by surprise and it suffered from lack of code at launch which kept the ball doing nothing in the ring too much...both things really polarized people. The game is very hard and I appreciate a challenge. I've always liked it and there is a lot to it when you start figuring it out. Too bad it suffered from JT's fate and won't be revisited again now, with a few tweaks it could be really good.
Finally the game everyone loved to hate, Popeye at 274. Once again, unique challenging game that most people pan without ever even playing the game. The weird environment theme didn't help things either. I've always liked it as is, but Popeye needs a code tweak to utilize the upper playfield better and it could be really good IMHO too.
