I would love to have the option to exclude my island from low end platforms, especially mobile. I don’t want to see my island in the very poor visual quality that a mobile phone can offer. I have played other high end games that have been made available for mobile, and they just look horrible.
Gameplay, feel and even basic level design works differently for mobile and big screen. There is a way to make great mobile games, but it is very different from games for console and PC.
Light scalability manager is a great attempt for a workaround and might work for some maps, but it just can’t replace a halfway decent shadow.
