If i make a fan "DLC" of the game should i post the entire game or just put the rpy files in a zip and a folder with the custom image the fan dlc would use with a notepad instruction on installing it
Simply.
option 1: put it as a simple download (entire game)
option 2: put the rpy files in a zip, add the Image folder called "DLC" and have a notepad request to move it to your game folder and if it asks to replace anything hit "yes"
