Metal Gear Solid 3 will probably always be a top 5 game for me. And I adore MGS & MGS2. MGS4 is a near perfect narrative conclusion even if I never want to play it again. Revengeance is just dumb fun.
But MGSV kind of put a damper on the series for me. I'm never really compelled to replay any of the series anymore which is a shame. I just feel like it leads to a whole boat-load of nothing now.
