Any good action rpg/fps tutorials?

Hey guys I’m looking for a good tutorial on things that cover mostly enemy AI, player controls like crouching, and if possible conversation options like the NPCs in rpgs like DA:Origins, Skyrim… you got the idea. Anything would do ebooks, videos… preferably in javascript but I can handle myself in C# aswell. Any ideas?

BurgZergArcade has a (quite lengthy) tutorial on making a Hack’n’slash.
