To my pleasant surprise, it was much easier to install on my old Windows 8.1 laptop than I expected (I had way more trouble getting 2 to work on there!). I re-bought it a few days ago because one of the discs on my original copy stopped working. Sims 1 Complete on Origin would be great. Then the other reason they don't fully support 1 and 2 isn't because they're oblivious to the sales they might be making (but then again: what can you really still charge for such old games?) but for the same reason you sooner or later will have to update to a newer Windows version as well - they remove support primarily because they want to earn money on the newer versions sometimes, the success of newer things is partly ensured by making older ones disappear. On topic: the reason Origin doesn't really offer support for 1 is because you'd have to use tricks to get it to run on newer computers (just like you have for all PC games from that time). So by all estimations, stay away from Windows 11! It's the Windows rule, isn't it? One good, one bad, one good, one bad. Even if it requires a bit of searching & testing to get some things to run (which in Windows 8, I felt you always just had to use desktop mode for, because in this horrifying app mode, I couldn't get anything to run easily, or the way I felt it should ).
I hated it from the first time I tried it, 10 on the other hand, I actually like a lot. Yeah this topic is old but ahhhh Windows 8 lol. 8 may not be the most popular windows either, but at least everything worked.
Pretty much everything ran oddly or not at all on it. I had 10 for about a week until I rolled back to 8. They worked perfect on my fiancé's PC before he upgraded to Windows 10. I would love it, I have all the sims 1 expansion packs.
