The scores went downhill after the Gameboy Advance games...
The touted as the best minigame collection out there... and yet not one has ever hit a 90.
The Mario Party games did change a decent amount between games, like most if not all the minigames. However the regular reviewer just sees it as "It's still just a collection of minigames."
It's not really the reviwiers fault that Mario Party doesn't have some minigames freak reveiwing it... like how most JRPGs have the resident JRPG freak. That's really more the editors fault.
They also made a lot of different changes to how the game works. A LOT more different then anything a Sports series had done to change things up year to year.
