Some days ago the guys from the MetalheadSoftware released some preview footage from their upcoming game featuring Ogre as the rendering engine:

BigFly Baseball

“We are developing a fast, light-hearted, atmospheric, and accessible baseball game. It mixes a unique cartoon art style with a simulation that is true to the sport.”
– Co-Founder, Metalhead Software Inc.

The game is driven by a custom made game engine (MetalTech) consisting of Ogre, bullet, Lua, FMOD and CEGUI. They are using 3dsMax for art&animation and OgreMax to export it all (in addition to a great many custom 3dsMax scripts as they told us). The team only consists of three guys, 2 IT guys and 1 artist. Nonetheless they managed to deliver a game that already looks great and fun in this stage of development and they obviously put in a lot of effort into the details like the stadium surroundings (Statue of Liberty, Air Force fly-by, …) and the cheering crowds (find more technical details about their implementation in the showcase thread).

BTW: MetalheadSoftware is currently in the process of striking a deal with a major 3rd party publisher. Best of luck with that!
