it's not about value, but moreso if a game cost less, more often than not, don't expect more content out of it. its not a guarantee as there are outliers, but purely by fundamental income, one will get content more than the others.

the simple comparison is compare games that have subscription costs vs ones that dont, this is especially true for MMOs and see how often they update. It's part of the reason why devs are pushing towards the (unsustainable) battle pass model. the battlepass is a way to prolong user engagement while forces the dev to push out updates more often than not. An example of a game being paid then switching to the battlepass model was Overwatch.

How many heroes were released in the base game/year time ratio vs what happened with 2. 1 was overall a better game, but 2 clearly pushed out more content in a faster time window than 1 did.

Games like BG3, and Terraria are some of the exceptions to that rule where it was content foward or decided to update several times without having paid updates. they are by far the norm. Hell Larians publically said they werent doing paid udpates, they are clearly far from the normal.
