A lot of games from the 7th generation were overrated, particularly by reviewers. We went from 9's and especially 10's being rare occurrences to reviewers handing them out for fun to honestly, very mediocre videogames. It skewed the scales for later games in the generation and we had that culture where a 7 instead of a 5 was considered "average". I like the following example for the PS3 -
Grand Theft Auto 4 - 98
Grand Theft Auto 5 - 97
This is despite GTA5 being leagues above and beyond GTA4 in pretty much every possible department. The reviews for Grand Theft Auto 4 were based around nothing but hype for the game itself.
Take the PS4 as an example on Metacritic.
The platform has 111 games rated 85 or higher. The platform has 497(!) games rated 75 or higher. Want to know how many games that are rated below 50? 57.
Reviewers have been frightened (or bribed) away from the correct scoring methods and it shows greatly in many, many videogames.
