More Gemini here.
First, I asked it to take a screenshot of Forza Motorsport (2005) and make it into a DirectX 6 era Racing Game from 1997-1998. I also supplied it with a screenshot of CART Precision Racing, just for the general aesthetic.
The only thing that really sucks is that I couldn't find a 4:3 screenshot with a period accurate car without booting up the game.
Next, Zuma for Genesis. I was never very good at Zuma (And still am). I'd say around 1992 or so.
Another game I found back when I had RealArcade (I think?) was Super Collapse. It's not perfect, but I love the space aesthetic. I'd say around 1992 or so, as it's more advanced than the early Genesis titles.
Another game I remember from my childhood was Hot Wheels: Beat That (Based on the PS2 version. I had the Xbox 360 version). This is what it might have looked like on the PS1, although it's not great, IMO.
Next up, another Popcap game, Atomica. I never played it, but I found it on an old archive of the Popcap site. I'd say around 1993 or so.
Next, Dinomite. Another Popcap software. This would be a fairly late Genesis game, as it's much more visually complex.
Next up, Bookworm, part of the Microsoft Windows Entertainment Pack. It came up with this first:
I felt it was too advanced.
A childhood game I remember playing was Pac-Xon, a flash game. I thought "What if Namco had made it in 1982?"
