MGSV has the best gameplay moment to moment but it’s bogged down (like nattie) by the open world design, the fucking RETARDED FOR RETARD ENJOYMENT ONLY storyline, and the lack of compelling boss fights. The FOB shit had potential but ended up being some weird mobile game tier bullshit
MGS4 is fanservice: the game and also has shit boss fights except vs Liquid
MGS3 is the best full package and best bosses
MGS2 has the best storyline
MGS1 is in a league of its own as a pioneer
