definitely play them in the order of release, as with anything. Some people say when they have kids they will watch the Episode 1-3 of Star Wars first but that would spoil knowing who Luke's father was, which is one of the best moments in the series (granted, they didn't need to reveal that at the end up episode 3, which is a problem I have with it. everyone knows who his kids were...ugh).
But, I digress...There are plenty of great moments with MGS2 that would be spoiled by playing MGS3 first.
Also, don't listen to vagabond, MGS2's controls are great if you have only played MGS1.
I wish I could experience it all again for the first time...I hope Kojima keeps working on games of that quality.
