I presume based on this some aspects of the story revolving around Team Rocket's activities were also further elaborated on or otherwise imprioved? I asked because the thing that holds me back from enjoying a lot of gen 1 remakes is no one seems to want to actually make Team Rocket have an actual motive behind their crimes. Yes making money is what they argue, they are a mafia sure sure, but the whole scheme they planned in Gold and Silver with the radio signal at the lake of rage gave them presence which can make them a legit worldwide threat. Not to mention that its at least assumed the anime's storyline relating to Mewtwo was soft-canon to the games, which is further reinforced by how in Ultra Sun/Moon, Giovanii is seen with a mewtwo during the Rainbow Rocket story. There was also a lot of hints of a war before the game's events due to a scrapped Soldier trainer class in the Nintendo Gigaleak a while back.
