Ranked by the strongest signal among each title’s copies released this month: modeled revenue, then followers, then reviews. Google Play’s installs-based estimate is too wide, and too new in a launch month, to rank by, so a Play copy ranks by its ratings. Highlighted stores launched it this month. “Console vs PC” counts days from the first release on Steam, GOG or Epic; a minus means the console came first. Chart positions are the best reached this month on the US chart (Epic’s worldwide one), and a copy with the same name but another developer is a different game and is left out.
