Forgot to mention this in last post. Once I get to a intermediate-high level of C++ I would like to create my own game engine. At minimum, this game engine probably won't see the light of day for a very long time since making an engine is a long and hard task. You have to handle performance/stability, GUI, functionality, and on top of this bug-fix all in a high skill coding language (C++). Then I would like to make a Lua-Python mix language to go along with this program.

What I'm trying to say is I will have a side-project to work on for the next few years.
