That's only really true for their first party games (EU4, CK2, etc) and Cities: Skylines. Most of their subsidiaries make very different games that follow more traditional development cycles.

I honestly like it. I like that they keep updating their grand strategy games. I put hundreds of hours into them, so paying $10 or whatever to freshen it up without drastically changing the core mechanics is very welcome. I don't like that for games I'll likely play once or twice, like the games they merely publish (like this one).
