Prosperous Universe is quite different from a typical incremental game, but it scratches the same itch for me. The game is very complex, and other players drive the economy, leading to some price/availability unpredictability that is interesting. Gotta keep your bases fueled, but you also want to wait for prices to rise or fall, and potentially use your ships to trade at other markets.

It's quite nonlinear in progression and there's a lot of ways to expand.
