If the game is simple, you can use the .ini file format. Editing is also simple, because it can be done with a text editor.
Thanks, I know A LOT of games use ini, but honestly have never edited one, what are the advantages? surley if it is simply writing values to the file, i will come across the same uglyness of writing to a txt file and again can easily get a little sloppy.
Are there any good web-tutorials on ini? quick google, didnt really show any promises :/
You shouldn't need a tutorial to make INI files, they're pretty simple and informal. They're just plain text files with name-value pairs.
As far as integrating it with C++, just stream to write/read file from the file.
