Well obviously RE5 for me which was a tragedy for me as a huge Resident Evil fan, but I think most of the RE fans kinda agree so only critically overrated I supposed. GTA IV probably in comparison to the series, but still a good game. But compared to the reviews, most definitely. That's just one of the cases where the game is still really good, but not the perfection they hold it up to. Same with Modern Warfare 2, although I think the game deserved more along the 8s rather than 9s.
