Am I the only one wondering why Bad Company 2: Vietnam is not a stand-alone expansion like what THQ/Relic has done with Company of Heroes & Dawn of War?

I truly believe that is the absolute best way to distribute expansions. Buy the expansion alone or add it to your existing game seamlessly... win win situation for everyone.

In my humble "e-pinion", they should've released this way, with Vietnam & BF:1943 as stand alone expansions for BC2.
