Not just that, but prerendered backgrounds, too.

All games could look like this if they got 48 hours to render each frame and their entire realtime render budget went to three character models, total and nothing else.

I mean, I dispute that games don't look better than that in the first place, too. Grainy embedded screenshot aside, the RE1 remake definitely doesn't look any better, even with all that, than the newer remakes.
