Story:Jurassic Park is a SEGA Genesis/Mega Drive game based on the first movie.
The game was playable as either Dr. Alan Grant or a Velociraptor (presumably the The Big One). Grant is the default character but can be changed using the 'Player' option on the game's main menu to swich to the raptor.
1993. I was 12 years old. I begged, BEGGED, for my first game system (Sega Genesis) for no other reason than to be able to play this game. I can still hear the sound of the t-rex roaring "SEGA" in the opening animatic. Pure nostalgia.
The T-Rex roaring 'SEGA' is one of the best things. I agree with Burnsauce. My brother and I would lose it every time. I only ever played as the raptor. Don't think we ever beat this one, sadly.
