We have a big game project using Unity at school. There are 12 of us working on it. My teacher seems to be convinced it's an important tool to teach students, since it makes students look from the high level to the lower level.

I can understand his view, and I'm wondering: Is unity such an important engine in game development companies? Are there a lot of companies using it because they can't afford to use something else? He is talking like Unity is a big player in game making, but I only see it fit small indie game companies who want to do a game as fast as possible.

Do you think Unity is of that much importance in the industry? Does it endanger the value of C++ skills?

It's not that I don't like Unity, it's just that I don't learn anything with it, I prefer to achieve little steps with Ogre or SFML instead.

Also, we also have C++ practice exercises, but those are just practice with theory, nothing much.
