I wouldn't say OGRE is a simple library, it's indeed a pretty big 3d 
rendering engine with a lot features. But it's only a rendering engine, 
not a full-fledged game engine, you'll normally need other libraries to 
create a real game (for sound, physics, joystick support, AI, etc.).

OGRE offers a lot of features so that you don't need to write most of 
the things yourself. If you don't want to take the easy route, it's 
still possible, but I don't think it's a great thing to do when you just 
discover a library.
For your problem, see for example :

Same thing, see :

I really fail to see how a good OO design is a problem.

Compiling is not particulary slow on my machine. I don't understand what 
you mean by "most of the programming is made inside headers".

You've got the manual and the API reference for that.

How so ? I use it on my machine with the official Debian/unstable 
packages without any problem.

You can find many good tutorials and articles on the Wiki. Fact is 3d 
game programming is not an easy task. If you are not prepared to invest 
some time in it, you won't go very far...

> Does anyone ever tryed one of these?

Yep, I did try OGRE and found it very nice, I really don't understand 
why you don't like it. In case of a problem, take a look at the Wiki, 
search or post messages in the forums or ask on the IRC channel. The 
OGRE community is very helpful.
