I am a HUGE metal gear fan and understand every aspect of the story and have played them all, beat them all multiple times exept the MSX MG 1 and 2, i have them both on my PC as roms but they are kinda.... unplayable lol. i would HAVE to use a guide to beat those, and i dont like to do that so i just watched vids of the important parts of the PS2 versions with all the new sprites and stuff (mainly mg 2, mg 1 i watched the end since it has no storyline) and now i have no reason to play them anymore. but yea, if you need help with any storyline aspects i can help.
