I agree that with each future iteration it should offer something better than the last. While sims 4 isn't open world it is way better graphically than 3 in my opinion (as we are commenting on our opinions here). And i'm not sure I understand exactly what it is you're looking for in this game other than for more of it to be open-ended, which by definition means having no determined limit or boundary. And if that's the case I don't think technology has reached that level even with the newest and greatest computer out on the market. Eventually I do think technology will get there but it just isn't right there now and may not be at that level when a Sims 5 (or even if a Sims 5) will come. As of right now I've had to replace my desktop about every 4 years to keep up with the latest and that's with upgrading over the years so yes, I will upgrade my computer if the game requires it but I'll do it when i'm financially able to and not when a new game that I want to play comes out. Till then i'll just keep playing what I currently have as I enjoy it just the way it is.
Personally I'm not even thinking of Sims 5. Still enjoying what we can do in this game. If I get frustrated with it then I just go play something else till I want to play the Sims again. And I do consider myself to be a long time patron of the game who I can assure you has spent way more than $1000 on it's entirety as I've been playing since summer of 2000.
