Gonna be honest; I know this game has a special place in the JP community but to me it doesn't seem all that good. Now I didn't actually play the game but after seeing several walkthroughs/Let's plays, it seems so lackluster. The characters are annoying, the game itself is butt ugly (even the dinosaurs), and the "revolutionary gameplay" is just a series of QTE's.
If I wanted to make a game that explored the darker side of JP, I'd have made a first person exploration based on the cleanup operations on Nublar post the '93 disaster.
