It's worth it, but only for a while...
The graphics are ok...If you running them on a good system, but their still kind of laking, sort of a been there, seen that sort of thing.
Game play is ok as well, just that you get to use your knife so many da*n times, all other weapons are rendered practically useless, In my opinion of course.
What I mostly enjoyed were the animations of a raptor lurking around or running at you to tear you to pieces. Animations made the game believable and realistic. AI wasn't too bad either.
Multiplayer is surprisingly effective, but still loose. Thanks God we don't have to deal with that wacky aim in the console versions, that will lighten things up dramatically and we will able to get some more pownage online!
Overall I enjoyed the game just a little, but I was hoping to get more emotions out of it.
