It takes the place of The Division 2, which was the second-best selling game before Mortal Kombat 11 took the throne. Ahead of both of them is Kingdom Hearts 3, which is still the best-selling game of 2019, and the best selling game in the entire Kingdom Hearts series.
Some other games on the NPD’s top-selling games for April list are Super Smash Bros. Ultimate, Sekiro: Shadows Die Twice, and six-year-old title Grand Theft Auto V.
Mortal Kombat 11’s rising sales don’t seem to be tied to increased player retention, however; According to SteamCharts, Mortal Kombat 11 has lost over 40% of its PC player base since the end of April. Where the game once had an average of 15,420 players playing the game last month, it’s dropped by almost half to an average of 8,802, despite the fact that it’s the second best selling game of 2019 so far.
This could be an issue for NetherRealms, since Mortal Kombat 11’s microtransactions make recurring players an important source of revenue, though the microtransactions themselves are solely cosmetic or time-saving.
This is only on PC, however; Fighting games historically do much better on consoles, especially the PS4. In April, Mortal Kombat 11 was the best selling third-party game on the Nintendo Switch as well, which is considered to be one of the best selling consoles in US history.
Whether or not the population decline on PC will be mirrored on console is yet to be seen, as is the effect of the population drop on microtransaction sales. Numbers are not available for console players, but looking at sales, NetherRealms is going to be just fine.
