Is that missing anything important because I am thinking of picking this up.
If you play Metal Gear and Metal Gear 2 (Metal Gear Solid is the THIRD game in the series) first, you'll notice a LOT of holes in the plot. I hope Kojima remakes those two to tie them into 3, Portable Ops, Peace Walker, and 5.
Here's the timeline again:
1964: Virtuous Mission (MGS3)
1964 (6 months later): Operation Snake Eater (MGS3)
1970: San Hieronymo Insurrection (Portable Ops)
1974: Costa Rica incident (Peace Walker)
1975: MGS 5 Prologue
1984: MGS 5
1995: Outer Heaven Uprising (Metal Gear)
1999: Zanzibar Land Incursion (Metal Gear 2)
2005: Shadow Moses Incident (Metal Gear Solid)
2007: Tanker Incident (MGS2 Prologue)
2009: Big Shell destruction, Manhattan Incident (MGS2)
2014: End of the Patriots (MGS4)
2018-2019: Metal Gear Rising
