A number of "TFU" mods tried to come out. None succeeded.
People are still going over the code and seeing what is in there. Right now the biggest thing going is called Open Jedi Knight. They are making JO playable in JA, and making unofficial patches for JO, JA sp, and JA mp.
Powering up force powers wouldn't kill the fun factor at all. As long as that is what you wanted. If powerful force was so bad then we wouldn't have gotten a TFU2.
