Well, I've just finished watching the 3rd film (no more than 5 minutes ago) and I don't really see why it's so hated, I really quite enjoyed it.
Oh well, that argument aside, I would personally like the game to be a sequel to the third and I would like the main (and playable) characters to be Alan Grant and Billy Brennan because I like both characters and I think that they make a great duo. Alan Grant is sort of like an Indiana Jones-like figure while Billy is just a likable sidekick. I really think that it would work.
Alan Grant would be a brilliant main character, because throughout the third film, just look at how many times he uses items to solve problems. Just a few off of the top of my head:
- Using the raptor eggs to get rid of the raptors surrounding them.
- Using the raptor voicebox replica with his mouth to try and shoo the raptors
- Using the flare gun with the gasoline in the water in order to shoo the Spinosaurus (though this was accidental, I think)
I know there were more, I just can't think of them, but my point is that Alan Grant used his brain to get out of situations, meaning that he'd be a great adventure game character because it's not just 'shoot-at-the-dinosaurs-and-hope-for-the-best'. And Billy, as I said before, just seems like a good sidekick.
Read that instead ^.
