The trend would be developers that are unwilling or unable to release a new game that is better than the old one (especially in formulaic series like a racing game), or that they intentionally withhold features in order to resell them again. I’m not saying there aren’t sometimes good reasons for it, just that it’s something I’ve personally noticed happening now that developers are leaning harder and harder into DLC, and now that games are stagnating in innovation and reasons to buy the next entry in the series.
Also for PAYDAY 3 specifically if you don’t have any familiarity with Overkill/Starbreeze I wouldn’t defend them on this one. They have chosen money over their players every single chance they could get, including breaking their promise to never include microtransactions in the game, and then breaking their promise in 2017 that they wouldn’t release any more paid DLC. In 2017 they released the Ultimate Edition with this promise, and in 2019 they went back on it. In 2019, they started releasing DLC again with the mission statement of “hey any money you put into this DLC will help fund PAYDAY 3 development”. The community immediately noticed that the DLC from 2019 onwards was of lower quality and more expensive, and although people frequently brought this up, others would defend it and say “yes, but we need to support Overkill or PAYDAY 3 won’t be made.”
They started development on PAYDAY 3 in 2016, so they’ve had 7 years to develop it before it released, whereas PAYDAY 2 has been out for 10 years at this point. The moral of the story is they kept releasing mediocre DLC for PAYDAY 2 because it was easy and lucrative, and it became such an addiction that they neglected PAYDAY 3’s development to the point where it released with barely any features or content even after 7 years of development.
