> the obvious go-to engine choice for indies and mobile developers What do you think has taken it's place?
There's a lot more indies talking about Unreal, and also Godot. Too early to see how much of that talk will translate to shipping finished games, though. Artists are excited by the potential of UE5, as Unity's rendering tech has stagnated somewhat. But making a UE5 Nanite/Lumen game is likely to be limiting your audience rather a lot, with high hardware requirements.
Is it ready nowadays? Looking at their showcase it seems I've played a few games using it without knowing.
