THEY DIDN'T MAKE MANY.
Also, just because there are a lot of very vocal IJ haters, does not mean that EVERYONE hates the game. The theme is awesome, and there are MANY IJ fans.
Lots of IJ fans + Not many pins = Supply and demand at its finest, folks.
When I throw a party, my IJ4 gets played TONS more than a lot of the games that the collectors swoon over. People pass by Twilight Zone, Cactus Canyon, Shadow, LoTR, ToM, etc etc...and go for the IJ4. Then, they all say: "I thought this game was supposed to stink? What's with all the hate?"
I'm not saying the game is awesome. It certainly has its flaws, and I can understand why some don't like it.
I just think that the haters are a bit over-the-top, and unrealistic on their expectations of how everyone else in the world should feel about the game. When you tell them you like the game, they stare at you as if you just told them that you like to eat live weasels.
