So if you bought the 3 parts of games separately(the base + both expansions) as they were released on impulse you still couldn't transfer it over? You would have to buy it as one complete package?
I ask because I'd be willing to buy diplomacy on Impulse if it allowed me to access trinity from Stardock. Otherwise there's not really any good way of going about it, since I'd rather not play from Impulse and it seems unfair to buy the whole thing again just to access it from an alternate source.
*edit*
Oh. Well that's somewhat disappointing, I guess I'll wait for the right options to be implemented. Thanks for replying.
