Have a look here . Geneforge 3 and Geneforge 4 are mentioned, though a lot lower than I would have expected.
Excerpts:
53. Geneforge 3 - This game is great. It's epic and nostalgic. Craving a non Japanese non Diablo RPG fix? This is the goods right here.
- Mike Kasprzak
82. Geneforge 4: Rebellion
It's really cliche, but they don't make RPGs like this anymore in the retail PC gaming world.
