3D Game Engine/Library

[Gator F]

I'm looking for a 3D engine/library. I've found a couple that I like but I want to make sure I'm not missing any good ones, so I've decided to ask you guys.

I want a engine/library that:

-Has a lot of good tutorials
-Is cross platformed
-Is fairly easy/quick to learn

What would you suggest?

SFML+OpenGL --- SFML is very cross platform, and connects to OpenGL quite nicely...

You can also use Unity if you want, although they force you to "donate" in order to get their best tutorials.

I've started SFML a few weeks ago and found that it is very easy to learn. They have several tutorials and if you run through those, you'll understand what you are doing fairly quickly.

SFML is really just an easy way of interfacing with OpenGL, so when you've gotten the hang of SFML, you can try and expand the features you use by adding more OpenGL stuff.
