Refurbish or replace engineered wood floor?

[mazdaq]

Renovating a flat at the moment. It has an engineered pine wood floor down in the bedroom and lounge. The previous owners didn't take good care of it - lots of paint, deep scrathes, scuffs and grime on it.

I'd originally planned to rip the floor out and put a nice new dark oak floor down.

Just had a thought though whether to sand down the rough patches and laquer it. Would that look any good or total carp? Don't particularly want to sand down the whole floor, just the rough areas.

Just after some opinions from the more experienced on whether this would look any good? Or should I just replace the whole floor?

Pine is soft wood (and rare to find a wood-engineered board with pine top layer, are you sure it's pine?) so would indent, damage more quickly again than hardwood.
