Here is a theory to hopefully be scorned at.

I think that young Will is the product of a simming mum who didn't quite make it to the upper echelons of the simming world and transferred her dreams onto her youngster.  Wanting to please his mum, he did everything, by that, I mean everything and anything to get his mama's dream.

"Apple" "MSFS" Manga Moon" "Will Redfern"  and no doubt countless other "personalities"  are one and the same.    According to his Apple profile he has been playing since 2000.  His BPS profile states him as being 17 which means he has been playing since the age of 8, next to mummy no doubt.  I am guessing that dad is not in the picture or rather vaguely.  Either that or he is lying, which he does often so no way of really knowing.

Lets just add a leftywillnot into the mix and see what sums everyone comes up with.  lefty Will not is a stubborn little boy who refuses to play nicely with the other kiddies and adults in the simming playground.  Will wants to be something and will do anything, absolutely anything to get his trophies and reward.  Will also wants to please his mum and make her feel proud. Will is now FA at Tsr, goal achieved.  If it isn't sad, it's pure evil. Will has many names and a fairly big lifespan so you will no doubt have many more profiles to deal with before you hear the last of him.

Could be wrong, often am....buggy (yes, as in buggybooz).
