I do have a few ideas, though I never played the game. Characters being attacked on a boat, scary dinosaur encounter in a lab full of broken incubation tubes, being attacked by flying dinosaurs on a metal bridge in a fog.
I'll accept the first one. I hadn't really thought of that before. But you're right. There is a scene where Regina and Dylan are attacked on the boat, like how Grant and the others were attacked on a boat in the movie.
I'm not so sure about the second one. I don't recall there being a scary encounter in a lab full of broken tubes in Dino Crisis 2.
As for the third one, I don't know. There are Pteranodons that attack, but it's not on a bridge, more of a catwalk above water (or does that count as a bridge?) and there's no fog.
Got anymore guesses?
