I'm probably one of the only people that loved Jurassic Park on the Sega CD. It was more like a point and click adventure game with some really awkward FPS sequences (if you could call them that) but it also had cool videos about all the dinosaurs by Dr. Robert Bakker.
Fun fact, in the book Jurassic Park and in the initial script, there was a river boat sequence. It was extensively planned in preproduction and teased as part of the plot. This was spread to the other 'tie-in' merchandise and park ride. This is why the universal studio ride is a water ride and why games that timed their release with the movie had river sequences. But as we all from the future know, it never happened. Budget overruns and shooting delays lead to script rewrites to cut out that sequence.
Oh man, do yourself a favor and watch speed runs of Flashback and Out of This World. Games that I spent forever figuring out that actually only have a few minutes worth of content, it's great.
