My family still has one but the image quality is terrible on modern big screen TVs because

1. It’s stretched out and native resolution of N64 is already tiny by today’s standards.
2. Unnatural aspect ratio unless you can set black bars somehow.
3. Modern displays have sharper pixel separation and colors don’t ‘bleed’ into each other as much which kinda helped the rough polygons of that era.

The result is a picture that is both sharp and blurry at the same time and gives me head aches after an hour or so.
