They are charging for an open source engine? Doesn't seem right.
Who is they? If you are referring to Runic, don't be silly.
They're charging for the content, music, man hours, effort, blood, sweat and tears that went into making this game.
And oh, BTW, the authors of Ogre3D are happy and excited that Runic is using their engine *commercially*. So just go back to your troll hole.
Finally, Ogre3D will be MIT License from v1.7. The Ogre3D folks specifically are changing the license to make it even easier for commercial and non-commercial developers to use the engine.
