What do you want

I want them to keep going with Sims 4. It's kinda buggy and I hate some aspects of it (like coming from the Sims Freeplay and seeing what on earth they've done to the babies in Sims 4 - you can literally buy one from build mode with the bb.showhiddenobjects cheat), but if they keep working on it, I reckon it'll be smoothed out eventually.
I'm not really open to a Sims 5. No option here's gonna please everybody, but I'd rather they kept going with the Sims 4 than rush out a disastrous game with Sims 5.
