I have to comment on this... while the tank controls are difficult to some, they are recognized as the staple of the RE series. The reason that RE2 for N64 had the "run in the direction you point the stick" controls was to simplify it for newbies... ie, you.It is a little bit like serious fighting games offering a "mash the right analog stick for special moves" option for non-hardcore fans.
With the later Cube RE sequels, remake and ports, they were back to providing only the real RE control scheme. Why? Because it makes for a more tense experience weaving amongst zombies. If you have a Mario 64-style control scheme, it is no difficulty at all just weaving through zombie hoards. It takes all the challenge away.
I really think the "tank controls" are fine by the way. They're just FPS controls from a third person perspective. They're the exact same controls in RE4 as well, but the camera has been moved to behind the character. Does that really change it that much?
The Mario 64 control scheme has its issues too. The direction you run is always changing based on where the camera is pointed, and if the perspective changes drastically, you could find yourself running in the wrong direction. (some games like Devil May Cry keep you running in the same direction even after the perspective change, until you move the stick in another direction, but that's rather clumsy too). It's not an inherantly better control scheme, as you make it out to be... just different. And it's a "different" most RE fans didn't want, because it would remove the tense challenge that is the point of survival horror.
