On Indie and Studio, Release Radar and the Wishlists page show what a launch could look like for your game.
We take the games most like yours that launched with a similar following, and look at the reviews they reached after their first week and their first month. From those we estimate the copies they sold, and show the typical result with the usual range around it. On the Wishlists page you also see the first week as a share of your own wishlists.
It is an estimate from real launches, not a promise. A quiet week, a strong demo and a page players love all push you toward the top of the range.
Still growing? We need a few launches of games like yours on record first. The forecast fills in on its own as they launch.
