I am planning on storing game maps to a text file. Each
of my hexes has a value (1024 possible for each) .
So, the map will have a height and width in hexes and
then I will read the map array one value at a time to
the text file.

There will be any number of maps available with different
sizes. The player can choose, edit or create them.

How do you guys go about this?

Thanks
