You will very shortly be playing Off-Road Velociraptor Safari. Why?
Because you travel back in time and run over velociraptors in an all-terrain vehicle, harvest their corpses with a giant spiky ball, and transport their meat back to the future. THAT'S FUCKING WHY!!
Did I mention that you, the driver of the aforementioned ATV, are also a velociraptor?
Suspension of disbelief? Believable storyline and/or plot development? FUCK IT. Let's run over dinosaurs in a truck!
This is the best damn idea evar.
