Not unless they use original game assets.
If they do all their own voice acting and all their own modding.
I dont knwo whether that accounts for writting as well they may have to change some of the game dialog slightly but I am sure if they are hard core enough fans to remake the game they will do it justice.
I was going to post a message sooner because I love the idea of this TC.
Really good luck to all of you, I am currently part of a TC team and we recently had a rather Epic disagreement (ALL MY FAULT) with the story... Yet we actualy worked through it without damaging any working relationships.
Aslong as you are all very inspired by the project you are doing then you will go far.
Good luck.
