Yes I know that Ogre is just a graphics engine. But it have "Addons" for OpenAL, ODE, CEGUI and etc.
What do you recommend then, apart from C4?
Setting up those libraries to work with Ogre3D isn't as simple as downloading and installing an add-on for some software. I recommend you go for a game engine that satisfies most of your needs in order to create the game you want to create. Why would you put together bits and pieces to create something that you already know you want, a game engine.
