No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $1.8M — a different platform, not this one.

Mega Man Legacy Collection

Mega Man Legacy Collection is a celebration of the 8-bit history of Capcom’s iconic Blue Bomber. Featuring faithful reproductions of the series’ origins with the original six Mega Man games, the Legacy Collection will remind long-time fans and introduce newcomers to what made Mega Man such a popular and iconic character. Mega Man Legacy Collection will feature all six games and much more. In addition to the six Mega Man games, Mega Man Legacy Collection features new ways to experience the classic games with the Museum Mode and new Challenge Mode. Challenge Mode remixes gameplay segments from all six games, with plenty of scaling difficulty objectives for experienced players to conquer yet serving as a good starting point for new players, too. Museum Mode contains a comprehensive collection of history, high-res art and original concept pieces – a mega treat for any fan of Mega Man and video game history. Additional hardware required for Remote Play.
