I was surfing Google for SimplePlanes builds, when I came across Jundroo on game-stats.com, and found a list of their games and the revenue from them.

Given that SP1's revenue over 9 and a half years is around 2.3 million USD, and Juno's is 1.1 million USD over just 2 and a half years (despite a smaller fanbase, I assume), I think SP2 will surpass both games, especially with the features in the development showcases. For now though, we wait for news of its release.
When SP2 comes out, we must make the devs millionaires!
@32 Yes, this is just Steam revenue.
@Kerbango well yes, I should have elaborated a little bit, but in short they’ve made a lot less than a couple million dollars off this game.
Although I kind of suspect that we’re seeing the stats for just Steam sales for the game, which will obviously be much lower than total sales across all
platforms.
@32 it does say NET revenue. Not gross.
I was going to say, "Go look in my profile..." But you already found me.
Also, I know that I purchased 4 separate copies of SP through the years. A pc version, a steam pc one, an android, and a mac.
Revenue minus staff wages and server/game fees
Jundroo be ballin🥶🥶
