Ahh man Makg! It's impossible to choose through all those... It took me a few minutes to decide that there can't be just 1 thing that attracts me most, it has to be all of them
But things that stand out are the alternate missions, the HUGE soldiers in VR missions (that'll be sweet!) and switching Snake's and Raiden's roles in the game. I'm gonna be buying an Xbox this summer, so good thing I won't have to wait for the PS2 version (even tho i support ps2 more, i just can't wait)
