I'm one of those Simmers who struggles with diversity when it comes to creating Sims. No matter how hard I try I tend to end up with small variations to the same basic mold. Pretty boring! I clearly needed help to overcome this problem - at the same time, I really wanted a way to make the genetics of grandparents play a role in how my born-in-game Sims look.
I asked my BF for help since he's recently started programming and I thought maybe he'd like a project to train his skills on!
The Plumbobber is an app that can help you create more diverse Sims by random rolls - but it also has a feature that lets you save data from grandparents and parents and then add them to a roll so that maybe you end up with a new Sim with the grandmother's eye color and grandfather hair color - of course, you have to adjust in CAS since it's not a mod - just an app to help you achieve more diverse and colorful Sims.

Of course, the genetics part of the app is not based on how real genetics work - we're just Simmers, not scientists
