I'm not sure how Levels.fyi work but those are great despite being paid in part with stock grants and bonuses.

However, Roblox itself is an exception. I'd guess the average game developer income to be much lower.

I love levels but the self-selecting group who reports their comp there cannot be used to reliably estimate the average, since they are not a random sample. I would guess propensity to report is correlated with higher TC.
