The Apollo 13 is probably my favorite machine actually(although I love them all!) People probably find the narrow lanes a challenge and you do need fair amount of skill to aim for appropriate targets. It is one of those machines that you need to spend some time on to really appreciate the complexity in the missions. I find the sound is great, lighting is very effective and when you get the 13 ball multiball blastoff it is sensational and it is made better with the shaker motor effect which feels like the machine is actually going to take off! Of course this all depends on the machine you are playing and the condition of it. I have played some 13's and they were not as captivating but I hunted for a few years before I found mine in excellent condition.
