In theory (not in practice) copyright law is supposed to give an economic incentive to promote the creation of culture with the "real" (again, theoretically) end goal being that it becomes part of the public works. But between the very extensive time lines given and there not being a requirement to provide a copy of the source code in the case of software you get this kind of thing.<br>PS: You might want to try emulating windows xp or 7 (probably 32 bit versions) to get the game running; I can't assure any results but I'd say it's worth a shot.
