Because I'm here, I just wanted to contribute to the discussion a little...
I'm currently playing on Legendary...
However...I'm doing this because the mods I've gotten are so beautifully OP that there really isn't any
point to playing on anything less...
The mod spells can pretty much level cities; Because of the level-ups, perks, smithing rings, the mod which allows you to wear as many rings and necklaces as you want, my IMPERIAL LIGHT ARMOUR is rated at 14 000+...And the weapons?...
Well...If you upgrade a God Weapon - courtesy of Akatosh - to the max (well, the max I had at the time...) then it's giggle-inducingly overpowered indeed...
McBoy one-shotted the first Dragon you fight on Legendary...
That's how OP these weapons are...
...
But that's just me...I'm quite willing to cheat my way to Level 81...Over-power my spells, armour and weapons...And still find the whole remastered element - with added beautifying, courtesy of Project Hippie - of the game utterly wonderful and compelling...
Far from being a humdrum experience doing these quests again, the mods have really made it properly fun...I'm having a blast, truly...
Challenge?...Nah...
Legendary...
