I recently used Tiled with RpgMaker and it feels like 2d sprite / tile editors are a solved problem. I also notice how 3d game engines note that they can also support 2D games. That space seems quite saturated and investing into 2D features seems like scratching one own’s itch. It feels like there is more upside to going all in on the 3d aspect, but potentially the 2D elements are quick to implement features to add to an engine’s laundry list of features.
