I'm only putting this little information on this thread because its related to a conversation I had with the article's writer about disablties (on the article site)
I asked about considering a poll for the idea of disabled sims and this is what the author said:
"That's the sort of thing that we might do if we were heavily considering it for a pack in the very near future. If it's just a more general poll, then we'd be worried it might disappoint players if it took years before we eventually did it. However, I had a conversation with some other SimGurus at lunch about this, and the general opinion was that including disabilities could be good if (1) it didn't use all our animation budget and (2) it was something players could opt into. There was one SimGuru who disagreed though, who thought it was too serious an issue. It was certainly an interesting conversation.
