X-Men is a great game. The only reasons it doesn't get more love is because the code started out in a horrible state and some people don't like a couple of the X-Men voices in the game. It has a great theme and it is a difficult game with a deep ruleset and varied shots...but it still has a little something for everyone. Anyone can start Weapon X multiball and have fun for instance. Plus the art package on the LE, Magneto especially is really good. Magneto might have the best backglass of any Stern game. X-Men is a challenge to me everytime I play it and that is what I look for in a game for home use. For what you get, especially in an LE package, an XMLE is a deal respectively. I thought X-Men was so good, I sold my Pro and bought an LE and it was the most money I have ever spent on a pin in over 25 games purchased now.
Fun Fact: The XMLE is the originator of the phrase "$10,000 by Christmas".
Funhouse is classic and a great playing game that was ahead of it's time. I have fond memories of playing Funhouse, but there is only so much there and it costs a premium price. It isn't deep and challenging enough to hold my interest in a home environment. If I had 14 games already and had money to burn, it might be a different story as it could do well in a larger collection where you aren't playing it all the time.
