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.

In C you have objects (structs). To use a method (action on object) you just pass a pointer to struct into the ``method'' like:

awesomeDB *db = awesomeDB_open ("filepath");
awesomeDB_add (db, "key", "value");

you can also make things like in C++ you call virtual methods (or something)

awesomeDB *db = awesomeDB_open ("filepath");
db->add ("key", "value");

All these with a clean, fast and simple implemetation
The two best FPS games are written in C (Return to castle Wolfenstein and Wolfenstein: enemy territory)

Finaly, what people call as OOP is not real OOP. As Alan Kay said, OOP is not about objects and classes but about messages, if you want real OOP try a language like Erlang
