New gameplay features and fixes for GPs refresh:

Yes! I need swimmable lakes in Granite Falls!

Realm of Magic
Making the realm itself a location with meaning and adding in more role-playing/story elements for people who go there would be nice, right now it's really just a lifeless hub.

I know Strangerville got alot of (really confusing) complaints but I loved the storyline there even though it was too short.

RoM needs it's lore fleshed out, and honestly I wish that having a mini-story in each world was standard because it makes the towns seem more "alive" and gives them personality beyond "build stuff here then ignore everything else going on around town."

I would also like to add hiking some trails like in snowy escape for granite falls. What's camping without hiking a trail.
Also the restaurant have high chairs for toddlers to eat. Have the hotplate working in a restaurant, have entertainment at the restaurant.
Get to work be able to take our sick Sims to the doctors.
Planet Sixam needs an upgrade badly.
Add more strange stories in Strangerville.
