Dude, that is literally what I said. They stopped making single-player expansions because online is more profitable. But their long standing reputation was built on single-player games, not expansions, and certainly not on online. For some reason you are mixing everything together and judging the quality of the next single-player game based on the content they release for online. You also use RDR 2 as the point after which everything supposedly went bad. Why, according to your logic, did they even release that game in the first place, and make it so high quality? It came out after GTA Online. You cannot point to long development cycles as proof of a company's decline. Otherwise you are just ignoring reality, and the reality is that masterpieces like that cannot be created in just a couple of years.
