Well, you have also interaction with the model. There's some ways (with 
callbacks) that the model gives you information.

I don't agree. OI is very easy to program. You can do very complex this very 
easy. Howeber, it's a bit complicate to understand how it works. But it's a 
question about graphics, not OI itself.

I agree that the games projects has a lot of features that OI lacks. But OI 
it's only a library to manage 3D models (also OpenGL). You need a widget to 
draw it. There are bindings for Qt, Win32,  GTK+ and  Xt/Motif. Not only 
Motif. About the sex appeal towards the developers ... not all the developers 
are equal ;-)
