I'd love a better system for finding sims and locations beyond the destination guide.
Hashtags might be a good option for making it easier to filter. I'd prefer to see a proper tagging system as opposed to sim descriptions ending in a jumble of words.
Perhaps a menu in the region settings that lets you fill out tags as well as additional dropdowns to help with filtering sims. Been a bit since I owned a region but as I recall there's only one category you can set.
