Although Rockman X DiVE remains unavailable in several regions (you can still download and play the English version here, though), the title has proven to be a formidable success for Capcom's five-year-old mobile division.
In their latest financial report for the quarter ending December 31st 2020, Capcom notes that mobile content sales were up 80.7% year-over-year. The boost is owed in large part to Rockman X DiVE, which recently launched in Japan in October 2020 (seven months after its debut in South Korea). The mainland China release of Street Fighter Duel also contributed to record profitability. Together, both titles drove mobile revenue up 4.7 billion yen. That's roughly $45 million.
All in all, Rockman X DiVE's profitability bodes well for the game's longevity. The title will no doubt play a large role in Capcom's on-going mobile strategy... just as long as it remains profitable. Let's not beat around the bush, folks; when (not if) the well dries up, Rockman X DiVE will meet a fate all too familiar to mobile games.
For now, though, enjoy it while it lasts. It could be a while!
