Nightdive's track record is stellar in fairness.
I've still got my PS1 copy of PO'ed and it hasn't aged well at all. I think the world was still clamouring for new and inventive Doom-clones at the time that people were willing to forgive clunky gameplay and unbalanced weapons, but this remaster will do it a whole load of favours.
Disruptor is another mediocre game that springs to mind, but was well received because it was the best-of-the-rest in what we now know to be first person shooters. That would be a cool remaster too - perhaps even Lifeforce Tenka, or even Sentient if they were feeling brave.
