Shouldn't a game have a sequel out before it's first release gets called "a new franchise/series" though? Not a planned sequel, because anyone can launch a game and say there are going to be follow ups. But if the follow up never happens, like in the case of "Ryse", can you really say that "Ryse" is a franchise or series? I don't think so.
If we do that his list will be reduced too. Like by as much s 13 titles or so. And he made alot of mistakes. Like Red dead is actually a Gen 6 game not a gen 7. Its actually called Red dead revolver.
And one can argue that this gen is very different wth its approach to franchising. Just look at rainbow six siege for instance. We have more continuing series this gen with a lot of DLC support expanding the game.
