With anything creative that you do, there is always that element of not knowing whether it will be received well or not. You just have to ensure that the quality is top-notch and give it the best you can, and not rush the project too.
I can totally understand LucasArts position though, as I do other game companies. It's also a bit of a grey area for some people because they believe that by putting a disclaimer into the game will guard against that. But I guess it comes down to whether they find out about it or not.
