I've thought about the next Sims game EA is doing and my main considerations involve two things:
One is anticipating that it does end up a free-to-play thing but then it's just called "The Sims" with no number or subtitle, just to fuck with anyone searching for the original as if that wasn't hard enough already. A lot of general "The Sims" searches get a lot of Sims 4 results since that's the current one so you have to go "Sims 1" or "Sims Classic" like looking for some ancient soda.
The other, which also involves the competitor games being made in a similar vein, is generally wanting to move toward "realistic" simulation and interactions and stuff, which that's cool and all, and having natural reactions to stuff like not always using the furthest away sink is appreciated, though I'm the type who also wants to see more weird stuff happen. To vaguely put it, similar to the level of classic Sims without forcing memes and marketing it as a purely wacky thing and all that, so there's some ground level to escalate from and return to. Of course I'd probably still mod it so I can have lizard robots and game characters and so on.
With that realism push though, it reminds me of when there were all these indie skateboard games coming out that were all based on Skate in terms of approach and controls, but to get something like the Tony Hawk games it apparently takes having some cute animal gimmick, and then the execution of actual gameplay in that apparently varies wildly, like between the bird game and the frog game that I've tried so far. I don't have any problem with cute animals of course, but now I wonder if a successor to the Sims I'd actually take interest in would follow that pattern, like would it be rats or ants or bees or something like that paired with the type of gameplay and simulation I'm after. Maybe robots or lizards, whether or not I mod that in.
More related to the realism thing would be city simulations, since I haven't seen much of any modern ones involve UFOs or whatever they're called now, or bargain bin Godzilla bootlegs, or futuristic elements other than bright white egg buildings with trees. There's always the classic games but you'd think they'd take more that worked from those in newer ones. And of course there's usually mods.
