Since when is 260,500 more than 360,094?
Why would you combine the sales of the standard and the remaster when making a comparison about the sequels performance to the original game? The remaster was released a year later on a system with no backwards compatibility, and no doubt received many sales from double dippers.
Use common sense.
Though if you want we can use your rules, because if TLOU2 gets a ps5 release too then that means TLOU2 will sell double the original game in Japan, wow what an incredible performance.
I know this doesn't fit your narrative of this game bombing so I'm sorry about that.
