is there any way you can make the other 5 episodes and Spear of Destiny and just get the game to perform a file-check and require the WL6/SOD files of the original game (for legal reasons) before all but the first episode is available, then add a save system and difficulty select screen (so we aren't locked on "I am Death Incarnate")?
This project is very promising and would really benefit from the full game implementation (provided that it's made to require files from the full game to run so Bethesda doesn't sue).
