MGS games are very much connected, so playing them in the order they were released is by far the best way to play the series, even if the games jump between past and present/future with different protagonists. ( Naked Snake/Big Boss vs Solid Snake)I was about to post the same, finally a MGS game (we did get Revengeance too) on PC after so long. I hope they at least release HD remakes of the first two as well.
But if you want to know Big Boss' story, MGS3 and MGS: Peace Walker are the most relevant games to his story, and Peace Walker is basically mandatory for Ground Zeroes.
Also, I'd just play MGS3 because it's a bloody terrific game. One of the best I've ever played.
