So... Uninstall Unity and get busy exploring Unreal Engine

Im joking, but that's what I should do..
It's free indeed for every use, but there's a "but", if you make >3000$ in a quarter (4 months) after publishing, you owe Epic Games 5% of that "profit".

You can get it here: https://www.unrealengine.com/ and I hope everyone starting in 3D game development, thinks twice before choosing Unity.
Don't get me wrong, Unity is great for starters, but if you are looking for that visual touch and/or you don't have 1500$ on your pocket to have shadows in your game... Unreal is the way to go.
