I wonder if this technique could be used to bring back PS1 esque pre-rendered background style games but with actual depth

The original paper doesn't work well with few-shot learning. I'm assuming that there is only one camera angle for each pre-rendered background. For single image to 3D, check out DreamGaussian. [1]

Pre-rendered in this context means you still have access to the full 3d scene so you can generate the full gaussian splatting model from that. The benefit here would be to lower the cost of rendering that complicated scene. There is a game called Fantasian (by the former FF dev) that uses real-life dioramas as backgrounds, I bet this tech would've been perfect fit for that too.

Oh I see. That's a pretty cool use case. Not sure how GS would perform on non-photorealistic scenarios, but certainly worth a try.

Probably, I saw one where they took scenes from movies and recreated 3D versions of them.
