More of a real Postal 3 instead of DLC on the same engine from what I read...or at least an expansion? I just don't like the term dlc, makes me think of all the games that call regular ass patches DLC.
We'll I'd not say real PIII, it's very much tied into the P2 and AW story. But yeah, it follows the same errand based missions as P2 did.
DLC is a bit of a broad term ranging from full on expansions like this to micro transmissions and heh, yeah in some case patches. But you're right we probably should be using the word expansion to make it clear it's a game in its own right.
