When you get the game, which do you intend to do first - multiplayer to get suit/weapon upgrades and unlocks while everyone else is on an even playing field or singleplayer because you believe it will be awesome?
Personally, although I intend to play MP for quite some time I will complete the campaign first.
I didn't find a similar thread, however the number of potential ways someone could word the title makes searching hard.
I watched 6 vids of a guy playing the leaked campaign and it was incredible.
Its more linear than Crysis 1 because of the streets (and many are blocked off), but those corridors are much wider than your average FPS game so you can do so much to approach your objective.
After playing the Multiplayer and completely dominating the competition, I think I might do Mp first and rack up a **** ton of exp, then when I'm burnt out from it, I can do SP which requires less critical thinking,reflexes, and timing. ez
