I have heard about a theory from Drk29 that Metal Gear Solid 1 and 2 are VR Missions.
Some of the things that he has stated about it include the footage from the trailers (the sinking Tanker and the FAMAS/Food Storage shootout) that wasn't in the Tanker chapter.
Drk29's theory states that Metal Gear Solid 1 was the player playing as Raiden while he plays as Snake.
Snake later states on the Big Shell about the Tanker/Shadow Moses VR Missions:
I doubt they accurately represent the events of that mission.
Which would seem to support his theory.
Is there any canonical evidence to this or is it just speculation?

There are a lot of references to Raiden undertaking VR training.
One interesting point is that if you play the Tanker mission you get the following conversation in the opening to the Plant:
However if you do not play the Tanker you don't get this line.
There is also a conversation between Snake and Raiden that states:
There are other mentions of VR training, but not specifically the Tanker mission in the game. These seem to be referring to the differences between MGS1 and MGS2's controls, but referring to the MGS1 controls as "VR Training":
And:
However nothing is explicitly said to state that MGS1 or the Tanker are VR, just these hints.
An interesting thing is that one game in the MGS universe (although not canon) does have a heavy hint at being a VR mission for Raiden, and that is Metal Gear: Ghost Babel (Metal Gear Solid for Game Boy outside of Japan). During Ghost Babel you play as Snake, however after completeing the Special Mode you get the line:
Raiden's real name being Jack and the game not making canonical sense hints heavily that this is Raiden doing VR.
Ghost Babel was also released the year before MGS2, so was probably made this way as a set up to MGS2, and MGS2's development would clearly impact the development team of Ghost Babel.
