I know that gameplay over visuals but for me all these Ratchet and Cland and Jak and Daxter and Nintendo games are cringe worthy. It's like if you had a decent car in some childish car body, it's still a childish car no matter how fast it can go and what functionalities it has.
Deus Ex (2000) - a game that pushes the boundaries of what the video game medium is capable of to a degree unmatched to this very day.
