so in anticipation for the next metal gear solid game, i've been running through the series to get myself all caught up
mgs - great for those who are new to the series
mgs2 - that end conversation blew my mind, best in the series so far
mgs3 - good gameplay, pretty good plot, i think the theme song is the best thing about it though
mgs4 - better gameplay, fine story and a nice way to end some seemingly endless plotholes and whatnot
currently playing peace walker, which takes place not very long before ground zeroes and phantom pain, and while it's a pretty neat base-building army management simulator i'd rather just plow through the story and be done with it. someday i'll probably get around to playing the old metal gear and metal gear 2, but to speed things up i just watched a movie of the gameplay and story. not to mention half the shit gets ret-conned as each game comes out anyway, so really just reading a sum-up is the best thing to do for those.
I mostly agree, but here's how I rank the series personally.
MGS2 > MGS3 > MGS > MGS4 > .........................................................Peace Walker (though I do love Fultoning random guys)
Looking forward to MGSV because it seems to be the last non-pachinko or slot machine thing Konami seems willing to put out.
