Grid Cartographer is a helpful companion program designed to assist you in playing classic grid based RPG series like Wizardry and Might & Magic.
It improves upon hand drawn paper maps with a number of useful features such as: unlimited map area and floors stored in one convenient place and unlimited notes per tile (pro only).
Grid Cartographer is available in two flavours. The free version provides a good taste. If you like it, why not upgrade to the pro version to experience the full range of features.
