In fact, if you add the people who played for free when it became part of PS+, that number goes as high as 1.3 million units. 9's notorious bargain-bin status has it going on sale for as low as 80% on Steam. For Mega Man Zero/ZX Legacy Collection, this is important. 9 on the chart?”, you ask? Because it provides a bit of perspective that sales numbers aren’t always the end-all, be-all that they're often made out to be. Despite my calculations, it's very possible that XLC1 hasn’t *quite* hit that 1 million mark on it's own just yet. However, while the pattern suggests that X Legacy Collection 1 sold the most of the two, it’s not ranked on Capcom’s Platinum titles. BUT this data is from 2019, so we can expect some growth from it. Mega Man X Legacy Collection 1+ 2 were reported to have sold 1.4 million units combined. This, too, is barring the spike caused by MMLC2 addition to Xbox Game Pass. We can assume, therefore, that MMLC2 sits at around 800k. However, in 2019, it was stated by series producer Kazu Tsuchiya that MMLC1 and MMLC2 sold 2 million units combined. Mega Man Legacy Collection 2’s numbers haven’t been reported explicitly. Once it's become a "back-catalogue title", perhaps. It's also entirely possible that Capcom stop keeping track after a certain point in a title's lifespan.
But even if they did, the numbers still wouldn’t line up as the PS4 and Xbox numbers, alone, match the total sales with no room for the Switch version (or 3DS, for that matter). 2020, which could suggest that they aren’t taking Steam into account. Now, the first issue we can see is that Mega Man Legacy Collection on Steam already surpassed Capcom’s own, official data as recent as Dec. There's nothing inherently contradictory with official data. First off, I will point at Mega Man 11 and the Zero/ZX Legacy Collection as the most “safe” stipulations.
