I was spurred on to create this thread due to the release of the most recent game, Metal Gear Survive, being today.
Anyone else fans of this series? I myself have played MG 1 & 2, all of the numbered Solid titles (including the $40 demo that is Ground Zeroes; curse me for being a loyalist), Peace Walker, and a bit of Acid and Portable Ops. And I've actually been trying to consider whether or not to get Survive, as I've heard good things from those who've played it.
My personal favorite games from the series are - in order of favor - MGS 3, MGS 2, and MG Peace Walker. Though I've thoroughly enjoyed every game I've played, even controversial ones like 4 and Phantom Pain.
