2 years ago Implementing this for pk3s might require disabling saved games and/or saving configs. Using the containing gamedir may work, but may also have security issues if people set up file associations to open files from eg their browser's Downloads dir.
Dragging directories may be viable, though I'm likely to insist that they be direct children of the exe's dir (automatic switching of gamedirs for multiplayer gets awkward otherwise).
Implementation exactly as it is in GZDoom, dropping a folder will attempt to run it as a -game argument. Bonus points for .zip and .pk3 support on this front.
