Ok, so technical question time:
The Wii version is based upon the Resi4 engine. How many zombies can the Wii put on screen at once in an enclosed environment using a modified version of this game engine?
I know that there are lots of factors in this equation, so it's not an easy straight forward answer. But surely someone with good technical knowledge of the hardware could give an estimate of what the Wii can do. Are we talking 50, 100 ,200?
Before we start worrying about how many zombies the Wii can't display, let's concentrate on how many it could display.
