@James
You were talking about adding T[XXX]C archives to your BBS. These archives include thousands of games (15GB, >10000 files) and applications (>3000 apps).
While this thread doesn't specify download link to the EOB AGA I have no problem with it.
However, it could be possible to require the original game and datafiles to be able to install the "AGA version". This way it would be perfectly legal IMO.
I see a small difference in what you were going to do, and what these guys are doing.
PS. EULAs are not legally binding in many countries.
