Making games. What to do after learning C++

Hi, I've just finished learning C++ and SDL. But... I don't think i can make any good 2D game like that. I've heard about desing patters, and OOP but they are too hard for noob like me.

Are there any language-agnostic books on how to make a game? Something like, ``This is the main loop a game needs to repeat: ...'', that sort of thing?
