I'd like to hear some examples of what is great about Space Jam.

It is not terribly desirable in the states, but I don't know a lot of guys who have played them much, and have only played the game once and it was an auction game that didn't work completely.

Spacejam flows very well. Polish the playfield and it is a fast game. All of the Looney tunes characters voices (bugs bunny, tasmanian devil, tweety bird, porky pig etc etc)  and the dot matrix videos/pictures of them makes it a fun game. The large orange basketball on the playfield is unique and when all the globes n rubbers are done, the machine is great.
Overall, a great fun game. The thing to remember i think about any pinball machine, is NOT to compare it. I say that because it takes away from the "new experience" that playing the new machine brings. Every time i play Spacejam i think it is a fun game.It flows well. The magnetised basket ball hoop shot with the playfield magnet that holds the ball in the air is great, the various modes are many. THE MORE YOU PLAY ANY MACHINE, THE MORE U LEARN ABOUT IT. THE MORE YOU LEARN ABOUT IT, THE MORE FUN YOU HAVE PLAYING IT. 

I find alot of people never give alot of new machines a chance. One or two games is not enough to make a fair opinion.

 I have bought all 25 plus machines for one reason and one reason only, to give any pinball player the most varied and the most entertaining pinball experience they can ever have. When i finish up with 50 machines, i hope to have a big meet and see lots of people say "I am glad i played that machine, it was a blast, Its nothing like i had been told, that machine was fun and i wouldnt mind one of them".  EVERY PINBALL MACHINE IS A BLAST.
