It's the same with the original Resident Evil games, I guess you can consider Re Darkside chronicles a Re2 and CV remake.
I still play DC1 sometimes, in all the years it's been made i've never seen a game like it.
Trespasser is a good game too I still have my copy that I bought in the 90's. I have my Dino crisis ps1 game too. I voted Trespasser as the best JP game simply because in spite of the bugs, it is the only interactive game that lets u walk around an ingen facility with dinosaurs and the JP story. The John Hammond memoirs are really cool too, you get a story of what happened to Ingen and Site B. People have also made levels for it, including one where you play as Nedry and have to get to the East Dock before the ship leaves!
I dunno if i'd like Trespasser remade. A finished Trespasser would be good though!

I'd like to see the additions of the extra levels they took out, the bugs fixed, and a slight graphical update too. Trespasser was never finished and was rushed out with the Lost World film, that's why it was never as good as it should have been.
I am looking forward to telltales JP game though. JP1 was the best film and it will be great to be on Isla Nublar and experience the incident from another point of view.
