Yeah, I'm really looking forward to additional mechanics in the DLCs already.I have to say, in addition to just being excited for the base game, I'm really read to throw money at whatever DLC they release for this. Since they aren't locked into pseduo-historical and can do sci-fi whatever, they'll be able to do some really interesting things.
The base looks great, but Paradox games become so much more varied and interesting when given a few content packs, that I can't help it.
