The Electric Playground
- "Its somewhat remarkable then that Project Eden not only offers an update to the genre, but also takes it to the next level with tons of challenging environmental puzzles, amazing graphics, and not one, but four lead characters."

Gaming Age
- "More time has been spent on making sure Project Eden included as many smart, engaging puzzles as possible, rather than incorporating half a billion polygons and the latest in vector shading techniques." Review by Patrick Klepek.

PlanetPS2
- "Lacks the full-on rampage of other action titles. "Halo" this is not. Combat is almost a throw-away sub-feature, and it shouldn't be." Review by David Hodgson.

GameZone
- "It's a massively built game but it seems more time was spent on creating the city than creating a driving story." Reviewed by Dylan Parrotta.

IGN
- "As far as style of gameplay, think "ICO," but without the atmospherics. It's similarly puzzle-intensive, and takes the cooperative aspects of ICO's design to an entirely new level." Review by David Smith.

Total Videogames
- "Whilst the graphics aren't exactly the most impressive seen on the PlayStation 2; the gameplay makes up for the lack in looks."

GamePro
- "Looks like a shooter, but at its heart it's a mind-busting puzzle game that transcends its own graphical limitations and delivers an intelligent gamer's paradise." Review by D-Pad Destroyer.
