Collections can also be a gateway for a new game. After the positive sales of the original Mega Man Legacy Collection and Legacy Collection 2, we soon after had an announcement for both Mega Man 11 and the X Collection.
However, what I and many, many, many other people want to see is a Mega Man Legends Collection and Mega Man Legends 3. How long have people been begging for a Mega Man Legends collection? To me it seems that people have been asking for a Mega Man Legends collection over another original, Zero, or X Collection. Mega Man Legends 2 sold poorly because it was after the release of the PS2, so it was overlooked. So despite how amazing and beloved this series is, Capcom refuses to make a third. Maybe releasing a collection on modern consoles and seeing it perform well we might actually get a third game in the series, much like how we later received Mega Man 11.
