Hmm... Years back when you wanted to do 3D, you licensed a "game engine". We used Twilight3D & Legus3D for several projects. These handled everything gamewise.
Today, "game engines" are rare, everything is broken down into individual "engines". You have rendering engines like Ogre, physics engines, sound engines. Often, Collision, AI, Multiplayer will be in standalone "engines".
With the way 3D games have advanced, it makes sense to split a game engine up so that it will be easier to port whatever you need to a new project.
I think "game engine" has become a term that is genericly applied to just about anything game related. ie, if you use B+, you write a "game engine" to handle the various aspects of your game and make it do what you want.
