This isn't really a challenge in the typical Sims concept. It's more of a challenge for myself.

Here are the rules:
1. I can only use packs and content from the world associated with that pack within that world. (example: I can only use Vampire pack items in the Forgotten Hollow.)

2. I can use Base Game and packs that did not include a world with every build. This means that most stuff packs and kits are free to use across all worlds

3. I do my utmost to stick with the architectural styles that relate to the inspirations for the world I'm working on. (example: Willow Creek is inspired by Louisiana, so lots should reflect Louisiana buildings.)

The goal is to redo and customize every single lot within every single world on one save file. This includes custom sims that have connections across worlds for every housing lot. Businesses must be owned by sims that are created for the save file.

I'll post silent speedy builds on youtube, and post the longer form of speed builds for members here. They'll be waaaay less edited, but will have voice over talking about the world itself, the relationships between sims, and what I was thinking about when building.
