If you teach yourself programming Doc_Savage then you should be able to create almost any type of game relatively easy (besides MMOs, of course).

What I mean is, tutorials are great, but they don't teach you much beyond the limited scope of the tutorial. Study a broad range of subjects, and you should be able to make any type of game you want

But back to the topic:

@wacek: saving/loading a game is pretty simple. In your code just use the function game_save() (to save your game) and game_load() (to load it).
