Sony was really dumb debuting a story driven franchise on a new platform with the fourth entry in the series. What were they thinking?
I don’t think so.
Here’s the thing; Sony’s the biggest fish in the PlayStation pond. But in the PC ocean, they’re just another fish.
Simple cinematic games aren’t exactly the types of games that draw the most players on PC. That plus they’re competing against a deluge of games arriving every day. They’re competing against subscriptions, and popular online series.
Uncharted wasn’t a great port, so it’s no surprise if the numbers aren’t immediately impressive. Sales will pick up as the price drops. Games have long tails on PC.
They thought that since it was a GOTY and sold around 20M copies or almost they could sell a handful extra million copies on PC with a quick port of the PS5 remaster, as they will very likely do (after its whole lifetime, not in the first couple of days).
Spider-Man, Horizon, GoW or TLOU sold slightly better than Uncharted 4 in PS4 and they aren't sequels (or well, in the case of GoW it's basically reboot that can be played as the first game) so I assume Sony predicted that this Uncharted collection will sell in PC less than these other supersellers.
The game barely has been released, we don't even have the complete concurrent user numbers of the first days and have no idea of launch sales. It's too early even to analyze the CCU numbers of the early days. We need more days to analyze launch sales and look more at reviews than to CCU to estimate sales.
And when comparing to other games, we have to compare similar timeframes, not a couple of days versus what other games sold during all their lifetime.
I also think that Sony will have considered that in this part of the year there are a ton of great new AAA games being released, so a full priced port of a 6 years old game won't have stunning sales at launch specially when being a 4th chapter of a story driven game bundled with its (originally) standalone DLC game.
