Since I'm in the process of upgrading to a new iMac with a graphics card that will allow me to play the more recent versions of games like Victoria(2), Civilization(V) and Hearts of Iron(III), I have a question... I bought Victoria 2 way in advance of buying my new iMac, when VPLtd was still active, but since VPltd appears to be in long term redevelopment (anyone know when they might be coming back btw?) my question is can I add the 'House Divided' expansion pack for Victoria 2, and the various sprite packs, via Steam, to a copy of the base game bought from VPltd?

Thanks in advance.
