You know that feeling when a game arrives and immediately makes you question every life choice you've made up to that point? That's exactly what happened when I picked up Jurassic Park for the Mega Drive back in '93. I'd seen the film twice—once with my parents, once sneaking back in with mates using the classic "we're just popping to the loo" maneuver—and I thought I knew what dinosaur terror looked like. Turns out, Spielberg had nothing on what BlueSky Software cooked up for Sega's black plastic wonder box.
The thing that hit me first wasn't the graphics, though they were proper impressive for the time. No, it was the sound. That Yamaha chip doing its absolute best to recreate John Williams' iconic score, but with this slightly metallic edge that made everything feel more urgent, more dangerous. When that main theme kicked in through my little portable speakers, it sounded like adventure filtered through a fever dream. Perfect, really.
But here's where things got mental—you could play as either Dr. Grant or one of the raptors. Most movie tie-ins just shove you into the hero's shoes and call it a day, but this game said "nah mate, fancy being the thing that gives people nightmares instead?" The raptor missions were absolutely barmy. You're stalking through Isla Nublar, hunting humans like they're particularly slow gazelles, using your claws to slice through anything that moves. It was like playing the villain in your own horror film, except the controller was getting sweaty in your palms and you kept looking over your shoulder even though you were in your own living room.
Playing as Grant felt more like what you'd expect from a film tie-in, but they'd cranked the survival horror elements up to eleven. You're constantly scrounging for ammunition, dodging dilophosaurus that spit venom like angry green fountains, and trying not to wet yourself every time a T-Rex footstep shook the ground. The way they programmed that footstep rumble through the console was genius—my Mega Drive used to vibrate the coffee table every time old Rexy was nearby. Mum thought something was wrong with the telly for weeks.
The indoor sections were where the game really showed its teeth, if you'll forgive the expression. Wandering through the visitor center with just a tranquilizer gun and whatever ammo you could scavenge, hearing raptor calls echoing through empty corridors… Christ, it was like being trapped in the best worst place on Earth. The way shadows fell across doorways, how the music would drop to almost nothing except your footsteps and the occasional distant roar—it was atmospheric in a way that most games from that era couldn't touch.

What really got under my skin, though, was how the game made you feel genuinely hunted. This wasn't your typical side-scroller where enemies follow predictable patterns. These dinosaurs felt alive, unpredictable. Raptors would disappear around corners and then ambush you three screens later. Compys would swarm in packs, each one individually pathetic but collectively terrifying. And don't get me started on the spitters—those dilophosaurus could blind you temporarily, leaving you stumbling around while something much larger and toothier closed in for the kill.
I remember one Saturday morning—probably around 7 AM because I was that kid who got up stupidly early to maximize gaming time—trying to get through the jungle sections without dying. The canopy overhead blocked out most of the light, and every rustle in the pixelated foliage made me grip the controller tighter. When a raptor finally did leap out at me, I actually yelped. Proper embarrassing, that. Good thing nobody was awake to hear it.
The weapons felt appropriately desperate too. Your tranquilizer gun took forever to reload, the rifle ammo was scarce as hen's teeth, and when you did find the rocket launcher, you'd hoard those precious shots like they were made of gold. There's something beautifully tense about facing down a charging triceratops with three darts left and knowing that if you miss, you're about to become prehistoric mincemeat.
But playing as the raptor? That was where the game went completely off the rails in the best possible way. You'd hunt in packs, coordinate attacks, and use your superior speed and agility to terrorize the human characters. The game actually encouraged you to be clever about it—pick off isolated targets, use the environment to your advantage, strike fast and disappear. It was like being given permission to be the monster under the bed, except the bed was an entire tropical island and everyone on it was fair game.

The password system was both a blessing and a curse. No save files meant writing down long strings of letters and numbers, usually on the back of an envelope that invariably went missing. But it also meant that every successful level felt earned, permanent. When you finally made it through the bunker sections without getting mauled by indoor raptors, that password was like a trophy you could show off to your mates.
Looking back now, what strikes me most about Jurassic Park on the Mega Drive is how it understood what made the film scary. It wasn't just big teeth and claws—it was the feeling of being completely out of your depth in a world where humans weren't at the top of the food chain anymore. The game captured that primal fear perfectly, whether you were creeping through darkened hallways as Grant or stalking your prey as nature's perfect killing machine.
These days, you can easily emulate it or even track down original cartridges if you're feeling nostalgic. The graphics might look a bit dated now, but that atmosphere? Still gives me goosebumps. Still makes me check doorways twice. Still one of the finest examples of how to translate cinematic terror into interactive nightmare fuel.
Proper mental game, that. Brilliant, but absolutely mental.
