Outdoor retreat is one of my favorite packs. It was the first one that I rebought when I started over with Playstation. It was interesting to play it without Seasons as it was originally played. I would like swimmable water there.
I would be willing to pay for a short list of updates that would be applied to multiple worlds. I would be happy to purchase a pack that did nothing more than add swimmable water and customized bar foods to the older worlds. I play on Playstation and have no mods.
I would buy $5 add-on packs that did things like add spa stuff to preexisting gyms, or add restaurants to preexisiting worlds.
I don't expect much in free updates. I am willing to pay for the things that I want.
