I just beat Metal Gear for the MSX2 today and wow... what a fantastic game. I've always been kind of drawn away from the earlier games for god knows why but I'm really glad I decided to play it. It's really well designed both in the stealth aspect and in the way the buildings are laid out/the whole general scenario. Plus all the items are cool and pretty fun to use.
Next up is Snakes Revenge, I know, it's not canon... blah blah blah, but it looks fun so yuh! Anyway, I've decided to go ahead and play all the metal gear games now in order until I get to finally play Peacewalker for the first time and then Metal Gear Rising. Although, I think I'll go ahead and skip Portable Ops and the Acid games since I don't have a PSP to play them on... it's too bad because the AC!D games look pretty good. Portable Ops looks like shit though :P
