Ultima Online, Everquest, Lineage...Blizzard definitely had a leg up with their brand recognition which boosted the genre to new levels, but it really wasn't a new idea.
This is a very common misconception, really. Yes, there are no new ideas. The fact that LG Prada sported a capacitive touch is only relevant for mansplaining. rewind.ai predates Microsoft Recall but who cares, really? The chances of an abusive spouse discovering it and using it to oppress further a woman is nil while Recall will be right in front of their eyes. AirTag was not the first stalking device but for sure it was the first to reach mass enough adaptation to get multiple women murdered. The list is endless.
