I already own EU2, EU3 + all expansions, Victoria + expansion, Hearts of Iron 1 and 2 plus expansions and EU:Rome, so my options are a bit more limited. I've been thinking of buying the EU:Rome expansion Vae Victis and Crusader Kings plus the relevant expansions. I'm just not sure I have the time to actually play them.
