You're a sort of human Barbie take-off who scavenges (sometimes very expensive) weapons and ammunition that have inexplicably been left lying about by other people, sometimes in places where presumably no human being has been for centuries.
You get to shoot plenty of rare animals from the top of a variety of food chains, plus quite a lot of dinosaurs, but you never get to put one in your tiny, tiny rucksack that incidentally, appears to be bottomless if the number of medical packs you put in it are anything to go by. Because showing a fresh dinosaur carcass to the scientific community just wouldn't be right, would it?
Instead of wowing the scientific community there's magic things for you to discover, because ancient artefacts on their own wouldn't be awesome enough - they have to be infused with crazy voodoo by the game-designers to make them awesome. This particular element of the game could be described as an allegory for religious fundies (ooh, it would suck for there not to be a god, etc.) Fairies at the bottom of the garden and all that.
You can also push and pull solid stone blocks many times your own weight and with no handles, outrun T-rexes and other shit.
And why are there so many medical packs lying around? And apparently all with the contents within their use by date?
