I'm inclined to believe that the content package will be substantial, since this is being shipped as a standalone game (unless we get Counter-Strike 2 or something... *x'ed fingers*). Like Vivi22 said, this is Valve, I can't see them shipping a game, even the console package, without it being worth a purchase.

I'm also with VeloZer0 with games in general. Maybe it's just me, but even games with little to no deviation, like God of War, are jewels I love coming back to year after year.
