It's a bit rich, given there are 14 paid DLCs for the latest Civ game, and they all have pretty negative reviews for being too expensive while adding little to the gameplay.
Yep, the DLC model can be quite obnoxious. Paradox has gone hard on DLCs and cosmetic DLCs are all fine and dandy, but some of the features locked into other DLCs (No espionage in Hearts of Iron 4 without a DLC, no amphibious tanks without a different DLC) are, IMO, core gameplay components that shouldn't require payment. But I was happy to pay for a DLC that gave Commonwealth countries unique focuses.
I like that their DLC model gives them the opportunity to support and expand games for so long. I don't like that their base games pretty much stink until they get at least the first few DLC though - there's not much reason to play CK3 when it's so content-bare and CK2 exists as a "complete" game with tons of content.
