Steam reviews are generally 90% memes or circle jerking.
Ghost Recon Breakpoint had mostly negative. The reviews all complain about either no achievements or the fact that the game was locked to their Ubisoft launcher first. Not real criticism of the game, especially considering most of what people complained about on release was fixed by the time it got put onto Steam.
It's now 7 months later and it's finally gone up to mixed with mostly positive reviews recently, despite no changes to the game.
Compare Breakpoint to Wildlands, it's not as good previous game, all of the recent reviews are still circle jerking but posting positively.
As soon as Steam embraced the memes and shit reviews by adding a Funny button its reviews went to shit.
