@ChristianOtaku Personally, I would love to see a disabilities pack! But... though I in no way imagine I would even know a fraction of the details that would be involved in such a pack, and as @jpkarlsen and @PugLove888 pointed out so well, we do know of so many aspects that would not be feasible or would be so extensive we don't see it happening, I would still love to see a a pack. I'd buy that pack.
If there was a way to move past the 'include everyone' aspect and hope, wouldn't it be great if we could get a compromise in a pack? For instance, If there was a base game & pack change to all worlds where all public/community buildings had a (yes, not fully realistic, but that's okay) rabbit-hole elevator to each floor other sims can visit. And all public buildings had a rabbit-hole entry door on bathrooms where the sim could enter and their bladder need would be met.
Then in the pack could maybe just include accommodations for wheelchairs? For instance, the pack would include several wheelchair-accessible houses that could be placed in the worlds, a wheelchair-accessible restaurant if they own Dine Out, and a companion/service dog if they own the Cats & Dogs pack?
The pack could include enable the sim in the chair to enter through normal doors in community lots. It could also include the ability to hire a live-in nurse/aid, several work-from-home or career options that are workable, and special items to add to a home you make for them that make features wheelchair friendly items.
Just a thought.
