Explore Unity

Inside Mac Games has a pretty in-depth look at the game development studio Unity:

One of the stand-out aspects of the Unity application is that OTEE has managed to bridge the gap between the total neophyte hobbyist's app and the professional designer's app. Unity's GUI combines some of the best aspects of working in the Macintosh OS with the look and feel of a high-level creation engine. Editors such as Dimension3 make tasks like creating floors and walls for game environments much simpler than Unity, with pop-ups and buttons to guide the user through nearly every action. Despite this ease of use, there's a feeling of restriction when playing around with Dimension3. The lack of viewing control and freedom of object movement, while making it very easy to make a nicely square room, almost squelches the creative juices. With Unity there's a fuller range of editing ability that gives the impression that the application wants to get down and dirty and show everything that it can offer.

There was recently a showcase of widgets from their recent challenge on OTEE's site. It also just added Windows publishing to it's feature set, making it more of a contender to engines like Torque. Unity definately looks interesting, although since I've only seen really quick projects it's hard to get a feel for it's potential.
