Unity, Leadwerks, and other game engines have great looking lighting systems in place which are far more than capable of being considered "professional" quality.For lightening, indeed , it's very very outdated.
But the strenght i find is the script to do lot of things ,and that you can produce any little type of game easily, all the documentation and examples
If you target visual lightening, you'll have ot work on yourself, it's not part of the package.
Like WED that is an outdated world editor, but depending on the game size you plan, you can make a game indeed !
Some people just make their own editor like the game SuperCan, but i can't imagine making some sort of world editor like that, i would prefer to make a game than putting 2 or 3 years for such editor, and within 3 years i could get borred, or let down game making to mobile ?
So i wouldn't take the risk and would switch to another engine giving me right now what i need.
It's only a matter of what you really need right now, not tomorrow
(because tomorrow , is always tomorrow ...)
