Maxis downloads, collected here for convenience.
Sadly, Electronic Arts have now closed the Sims 1 part of their website. While some of the files are apparently still available, hidden deep within the tangle of web pages that have not been removed, I personally cannot log in and download them at all now, even WITH my old and formerly working password. This doesn't seem right, considering that we PAID for these games. But it does seem to be par for the course.
I have put together the files I've collected here, hosted not now both for convenience and as an archive to Maxis' great work.
