This is something I have been worried about myself. Even the commercial success of the franchise is now questionable. Sales have been falling since the first game. All 4 one just now reached 1 million in sales, while ACiT did it in around 6 months. All4One took 2 years. Though I think the popularity will rise back again with the release of the new movie in a year and a half. I hope we still have new better R&C games to come.
