Mafwek: Oblivion is just as easy to break as Morrowind or Skyrim, all three games are very exploitable if you know what you are doing. But I would ask which of the three games is the most fun to play without using exploits? Oblivion seems to have the most fun gameplay loop over Morrowind or Skyrim, even though it is worse than them in pretty much everything else, IMO.
MysterD: Curious:
Are there any mods for Oblivion, Skyrim, and Morrowind that can block the player from breaking the game?
You can easily break the game in Morrowind if you kill a main quest important NPC like Lord Vivec, if you can reach a high enough level and take him down. Good luck w/ that - but, it can be done.
Killing Vivec does get you an item that allows for an alternate solution.
Of course, getting that ending involves a permanent loss of max health (which, based on dialog, was really intended to just be a loss of current health, as it suggests you use Fortify Health if you can't survive it at max health), but it's still possible.
Or you brute force the end by using super potion and similar exploits to get your health high enough to survive the massive damage that that artifact is supposed to prevent.
The Skyrim Unofficial Patch removes that game's super potion exploit, but there's another mod to re-enable it.
PookaMustard: Whinging over "Body Type A/B"? And going as far as to mod it out? Seriously?
Actually, I'd like to know if there's a way to mod this *in* to the classic version.
dtgreene: One thing, however, is that Morrowind is the easiest of the three games to unintentionally break, while Oblivion contains some counter-intuitive mechanics (behavior of damage + weakness in same spell, Fortify Alchemy) to try to prevent exploits, arguably going too far in that direction.
You mention what happens if you know what you're doing, but if you don't, Morrowind is the easiest to break and Oblivion the hardest.
(By the way, in Oblivion my favorite armor enchantment ends up being Fortify Luck; that stat has significant benefits before maxing out all your important skills and (even in the remaster, apparently) is the hardest stat to permanently increase.)
Mafwek: Well, I unintentionally made myself completely immune to magic in Oblivion by playing with Fren... Breton master race and equipping Mundane Ring, so I don't know about that one.
That does require that you make a particular racial choice, and that you get an item that won't spawn before level 20. (Although it dies have a reliable source, but only if you don't fight what I consider the final main quest boss before level 22.)
