It does feel like a thinly veiled add me thread, but it does quite a bit to entice the reader and doesn't end with a link to some obscure web site scamming for info.
Honestly this thread is rather harmless.
I enjoyed reading that you tried to make it accurate to the show.
You can take inspiration from....let's say "The Simpsons Hit and Run" Videogame.
That has a drastically different placement of buildings throughout the game.
The new Intro has a more detailed and consistent placement with the billboard being one of the few things that changes....that said every episode is it's own springfield.
The only constant is that The Simpsons House is next to Ned Flanders.
Some episodes have the next door neighbor as Mrs. Glicks house, the Powell's, the regular Brown House, the Cool Brown House ...and George Bush lived across the street from them in the special White House.
In the StoneCutters episode it shows the Simpsons back yard as being right behind the Springfield Nuclear Plants parking lot...
Other episodes have them elsewhere, the Simpsons movie has the old Sea Captain living in a Houseboat in the Suburbs etc.
Things change considerably often in the show.
So a degree of curiosity does pop up in what episodes you took Inspiration from.
