I noticed that Nightmare Skill Level is treated cheaper by Nerve Software and Nightdive Studios respectively.

Yep, you heard that right. Nightmare skill level originally forbade most of the cheat codes except IDDT and IDCLEV until Unity Port allowed the rest of them to be enabled. To make matters worse (or better?). Doom + Doom II: KEX Edition removed the "This skill level isn't even remotely fair" confirmation from this version.

I may sound old-school-ish, but Nightdive should add a new parameter for the Difficulty Modifiers Page called "Allow Cheats." If that parameter is turned off, only IDDT and IDCLEV can be used when the game starts.

Can't you just not use the cheats when playing Nightmare?

I mean, I think the bigger problem if anything is that not only do the "beat [campaign]" achievements only check if you beat the final level, none of the achievements care if you used cheats.

That said, I'm for additional difficulty customization in both directions.

Let’s see, Unity actually started with the broken Nightmare difficulty of previous ports before being fixed, multiple source ports (including PRBoom+ and ZDoom via console command just to name a couple) allowed cheats on Nightmare, Nightmare difficulty nowadays has more respect than it ever had in the 90’s & your suggestion to add a “difficulty modifier” is not a very good idea as it would blanket make the lower difficulties break as they never had the “Nightmare” Check.

I assumed that if implemented, cheats would be allowed by default; i.e. that it's an opt-out setting.

speaking of cheats, what's with entering IDMUS## into cheats menu and it giving out message "your memory serves you well, but nothing happens"?
yet when typed directly in-game, music does change.

Its a case of IDMUS is a bit more context sensitive compared to the rest so wouldn’t fit in a cheat menu full of usually single toggle codes, IDCLEV has a similar message in the sense it tells you to use the level select instead.

All the Modifiers are opt in by default (as in, they are set to off by default). You would need to make it specifically a “allow cheats in Nightmare” modifier but then it would only appear in one difficulty by default making it a bit pointless programming wise. Besides, this is not 100% vanilla Doom using all the vanilla code.
