I wouldn’t say I quit, I still like it to make a mobile game in a week and releasing it.
But Unreal Engine 4 is just way superior when it comes to programming. I like how easy you get scripts going in Unity, but I hate how quickly **** becomes not managable anymore, due to the dragging scripts into entities system.
Having the whole code base in front of me is just a must for bigger projects and Unity just fails in this department for me.
