They are just using the goodwill from the existing IP to leverage all the suckers who don't wait for reviews to run out and buy a game (or buy a game in the future based on what they dimly remember from their youth) and only afterwards realise theat they've been had.
It is a purely cynical exercise, seen recently in the flood of films made from seventies tv shows (Brady Bunch, Professionals, Mission Impossible, etc etc).
Just pure scorched earth policy short-term commercialism ...
