Geneforge 4 - Preview @ Inside Mac Games

Inside Mac Games has a preview of Geneforge 4 based on the Mac beta.  Here's a snip on some of the differences to prior generations:

First off, Geneforge 4 completely departs from past games in the series by offering five classes to pick from (as opposed to the original three): Warrior (same as a Guardian), Infiltrator (Agent), Lifecrafter (Shaper), Shock Trooper, and Servile. That's right; at last you can truly represent those poor oppressed Serviles, funny nose and all.

Secondly, very soon after starting a new game I realized that Geneforge 4's world is much more active and interesting than past Spiderweb games thanks to a large number of graphical enhancements. Two of the most obvious ones were weather effects and small environmental animations.
