Do we get the source files?

I think I already tried this before (at Ubisoft), and the response was very generic.

What did they say then?

Nevertheless, it's worth trying again, as a lot of time has passed.

Perhaps, the format of the request should be changed:
present logical arguments + emphasize that this is of interest to many
Even if they refuse, at least they will know that the game is still popular among fans. Who knows, maybe they will make a sequel.
