I was an avid Paradox player, but I pretty much stopped when they started pumping out DLCs at a rate I couldn't follow with, in the CKII/EUIV era. I played EUIV a bunch but I probably still have more hours on EUIII
I bought CK2 years back, in a pack with all the then-existing DLCs. Then they added a lot more. I'm just defeated, I give up. I refuse to deal with products that don't have a clear feature-set and pricing. You don't have to deal with those studios when there are so many out there that don't actively try to squeeze you.
