A lot of it is just nitpicky bullstuff. There's another video where someone does the same exact thing for things GTA V has that IV does not. Both videos are equally handicapped. Each game isn't supposed to be your typical sequel, being a rehash of the previous game. Rockstar has said before that they like each game to stand on its own and have its own selling point.
Anyways, I also didn't like how random events were handled in GTA V. They were obviously trying to emulate the ones they had in RDR, but they ended up being "unmarked Strangers and Freaks missions." They all only happen in one set location, and once you complete it - it's done. In Red Dead Redemption they were truly randomized, and infinite. The world didn't die once you had seen each event.
