4. Metal Gear Online V2
Metal Gear Online was never an enormously successful component of the MGS franchise, but it was fun, albeit with a few qualifications. The gameplay was for sure too slowly paced in order to preserve the stealth elements, but it was also great fun using your wits and experience in the MGS games to stealthily take down a fleet of enemies. Though I suspect Kojima and co. may have abandoned the notion of another MGO game after the mixed reception to the first one, I think it's still worth another shot. Granted, I'm sick of games that sacrifice single player development for multi - especially in a series as story-driven as MGS - but wouldn't it be fun to try MGO V2? A refined take on the original idea that rectifies all those nagging issues and ups the pace a bit?
