Where should I start Game Dev now?

So, I have CS degree, MMO dev experience in a native language (think WoW and its scripting language (LUA?), except standalone,) and a lot of 2D games developed in C# XNA.

I want to move to C++ but I'm not sure where to start. At the moment I'm looking at GameDev.net.

If OOP is about messages, then CLOS isn't OOP? I've always suspected that it's too good to be clamped into the same boat with the Javashit. What do you call CLOS's paradigm, then? MetaOOP? SuperOOP? HyperOOP?
