I'm forever getting 'pretty far into' a playthrough of CK2 or EU4 and then having Paradox release another expansion that means I need to start again from scratch.
the other day, I booted up steam, to find that it was downloading an update for Crusader Kings 2. I checked, and to my surprise, there was another expansion that had been released, which I had missed, as it was only announced at the beginning of January.
Needless to say, it probably will break my existing save games, both normal, and a warhammer world mod that I have.
lol.
