Eh, I honestly like their DLC policy. Basically, every year or two, I come back and buy some DLC on sale and basically treat it like a new game. I'll play EU4 for a couple hundred hours, take a break for a few months, then buy some DLC for a couple hundred more hours. I'd much rather have this than new releases every few years, since I can just add new systems instead of dealing with a bunch of UI and core system changes.

The main problem I see is that they launch things half-baked, which means their games and DLC aren't worth the price at launch, and by the time they're properly patched, they're on a pretty significant discount. I think they'd do much better if they delayed their releases until they're actually done and cut prices by 25% or so. If they consistently delivered high quality products, I'd probably buy near launch.

The next biggest problem is a shift toward flavor DLC instead of actual mechanics. While I like the flavor, I mostly come for the new mechanics to play with, and at least in EU4, they've been reducing the actual amount of new gameplay with each DLC.
