I owned an Iron Maiden Pro for a year and a half and sold it to get a Jurassic Park Premium and haven't regretted it once. Maiden is great but after a while most of my games started feeling the same in terms of progression. Jurassic Park's software is perfection and you rarely have 2 games that are similar. I agree 100% with Yancy's post. I still enjoy playing Maiden and if I was a bigger fan of the theme I'd consider picking another one up. In terms of Keith's games JP is my favorite by a pretty wide margin but is followed by Godzilla, and then Maiden and then way down at the bottom is AIQ.. that is one that I just can't get into.
