Unfortunately things were different with ARMA2. The game didn't use Steam as a matchmaking system, but a own multiplayer lobby instead. Therefore there were a Steam version of the game and a version that didn't make any use of Valve's service.

In CoD however they use Steam for matchmaking, so every user (even the retail ones) has to use Steam.
