Well, having a look at the Minimum system requirements in the BUY THE GAME
section at
http://www.mortyr2.net/
the game requires at least a 3D accelerated graphics card of GeForce 2
class. Your onboard video (Intel82865 Graphic Controller) doesn't meet the
requirements, and that's probably why you're receiving the "not initialized"
error.
I was unable to find the exact motherboard model you mentioned at Biostar's
site (I868G-M7), but the closest I could find was the I865G-M7
http://www.biostar.com.tw/products/mainboard/board.php?name=I865G-M7
If your motherboard has the same expansion slots as the in the link above,
you have an AGP (4x/8x) slot. You will need to purchase an AGP4x or AGP8x
video card and install it (along with its most recent drivers) in order to
play not only this game, but other games that require a video card as
opposed to onboard video.
