If you played Rare games from the 90s you would understand.

Also those games while not considered 'bad' weren't exactly considered system sellers.

the things Rare has been known for were platformers (Banjo Kazooie, Donkey Kong) and FPS games (Goldeneye, Perfect Dark).

Perfect Dark Zero in 2005 was probably the last title in either of those veins, which was a launch title for the 360 (soon to be 2 consoles ago!)

Sea of Thieves is certainly a feather in their cap, it's just a bit disappointing that we haven't been able to see Rare take a modern crack at the things they were so known for, if that's even possible now.

Most of the Rare staff responsible for those games have left in the decades since (many of them formed Playtonic, which was the pitch behind Yooka-Laylee)

To expect a company to produce the quality/type of games that they made 20+ years ago is a bit unfair, don't you think? I'd venture to guess that the folks behind those games left the studio along time ago anyway.
