Being honest, I wouldnt doubt that if this site was around in 1994 someone would post some shit on how doom 2 ruined the series by adding the super shotgun or shit like that
Master Levels is pretty bad, if you ask me, the maps by Dr Sleep (Geryon, Minos's Judgement, Nessus, Vesperas and Virgil's Lead) are the best ones.
Also I kinda agree on NRFL, its great.
I would put it above Sigil 1 and 2 to be honest if we consider it any level of "official"
Edit: I just remembed the funniest game review I can think, even in 1994 journos were retards
