It still isn’t a good reason. (Major) remakes don’t make sense until a generation has passed - that is, at least 15-20 years later. There’s no point. Last of Us was a silly one to do, even if it looks better now. They shouldn’t even be discussing a Black Flag remake until after 2030 and earlier in series game remakes are released.
