MGS on PS1 is beastly, for sure. My favorite MGS games are in order:
I might finish up some random quests in Skyrim that I haven't completed or finished up. I pretty much got them all done but I Googled it and there's a few stragglers that I haven't picked up over the 150+ hours I have on this character.
Yeah the PS1 ones rule, the best thing in the whole series is the psycho mantis fight having to put your controller in the 2 player slot and he reads your memory card and system frm what you have playing and been saving. Also liquid snake is pretty sweet.
