Turok 8)
 

I was hooked for over 2 weeks, rented it 2 maybe 3 times :D

Holding the controller is a little funny though.

(Left thumb - look, right thumb on c-stick for moving, side of right index finger for button management, and obviously right middle finger for the trigger)

Overall the graphics were fine, gameplay was great (AFTER you get used to the controller holding) and some of the chapters really get you goin'. It's also suprisingly long...

the loading time is way too long...

When i looked at the game it looked good.
