I want to thank you for asking this question, and also explain why for the, "just google it" crowd.

I have believed for the last 10+ years that this meant combat-rpg. My ignorance would never have been fixed if someone hadn't asked the question in a place like this; I never would have googled the answer to a question I didn't have.

How many more serious questions out there would benefit from more discussion, rather than individual research?

Alright, take my soap box from me.
