I tried Spore in like 2020... didn't really get into it though. It suffers somewhat from its still-early-3D graphics, and somewhat from plausibility-of-the-faux-genetics-or-lack-thereof.
So I have been firing up Sim City... I'd forgotten about SC4's performance issues. The mechanics may have aged well, but the code itself, like many Maxis titles, didn't, and the
Sims style UI doesn't fit it as well as it fits
The Sims. Will I revisit it, after getting it to run as smooth as possible, and likely setting up the NAM? Maybe, maybe not. But I did find the
SC4 Succession Session from 2013-14 on this forum, which was a fun time.
But I also installed Sim City 3000, from the original CD, and... it runs well on modern systems. I loaded up the largest city that ships with it, with 2 million residents, and the graphics are smooth (aside from the like-in-1999 issue of taking a while to load textures initially). The simulation speed is a bit variable, but it's a very large city; our SC4 succession session maxed out at about half a million, though a flatter map could have gone higher. And it's the one I remember so well, with its advisors and music and historical evolution of the city, which I thought SC4 had, but it was just SC3K.
That only emphasizes that Maxis has a huge opportunity to make a new city simulator that runs well on modern systems (modern resolutions, running graphics on a separate thread, multithreading where possible for scaling, not having the "EA Games - Challenge Everything" video play every time you start the game until you disable it). And maybe that one they made in 2013 does some of that today, but from what I've heard while it surprisingly does run offline now, its too-small-of-a-city problems never went away.
And yes... there are still a lot of good old games missing. I used to follow GOG's blog as it seemed like every week or two some old game was being dusted off, but now there are so many other things in the blog, and so much more content, that it's impossible to keep up so I don't try to.
