I loved Trespasser as a kid, but as far as realism goes, I never understood why there were so many Raptors. I'm sure someone counted them in the game, but holy mother... moreover, they had to be massacred for the most part. That was the only thing I never liked about the game: mass murder of the Velociraptors.
Anyway, I remember I used to envisage a sequel called 'Trespassers' (how original
) where you'd be part of a team and every decision you make affects who survives. If you are good enough, you may be able to save everyone, but just as well you might be sole survivor.
But this is as far as I got.
