vsing people on steam

Hi, Men of War is currently on sale on gamersgate, however the game of the year edition does not activate on steam.

This may be a silly question but I want to make sure, as to not waste money.

If i play Men of War off steam, does this still use the exact same servers as those playing on steam?

Furthermore is this the same for all games? thanks

Yes, MoW isn't supported by Valve, any MoW game and any version of the same game uses the same servers/multiplayer system.DanielDust
