My ideal game dev environment would be a place with nice weather (low pollen), a variety of good food options, a 2nd job that pays the bills but requires little to no mental effort. A reason to sleep all day and stay up all night to avoid daytime distractions and take advantage of the quiet of night.
I never got to do this but some of my college friends did and they speak highly of it:
Graveyard Shift Hotel Desk Clerk in a resort town.
It would be fantastic place to live with good food options. Banging away on your computer all day looks like what you are supposed to do. Occasional social interactions prevent you from felling like a hermit. Room and board more or less provided by employer. Valuable networking connections possibly walking in through the front door.
Why yes I am developing a steam punk MOBA, you seem to know an awful lot about the Unity editor.
