Well, that DVD preview was taken from a March 2001 build of the game.
So are those screens above, because thats when they were put there by Videogames.com...
I think (and hope) that the graphics (particulary the dinosaurs) are improved. Looks good though, nice textures, and finally has an interesting, non movie related plot! Thats right, doesnt go along the JP3 movie plot, but one entirely developed for the game!
The game is also now called JP3 : Survival
