jamotide: WTF I have no arguments? Have you even read anything? What about the fact that many level scaled games have been improved by mods while NONE have been improved by adding level scaling?
No you pretty much don't. (edit / correction:) the only arguments were incentive to level, which oddly enough most people don't seem to have a problem with, be it TES or other lvl scaled games, and "strategic possibilities" of getting better loot you usually shouldn't be able to get that early. (/edit)
You bring opinions, not facts or arguments. You claim it to be so, because it doesn't enhance your play style, therefor it is, while ignoring other play styles that benefit from it.
You claim level scaling in Fallout would have sucked. That's an opinion.
I brought reasoning why it "could" have worked. I wanted to know if it's possible to head straight south and then work your way up north. You pretty much ducked it. So I'd have to go with the claim, it being lvl-walled. Successfully going through a lvl-wall with a run or die approach, is NOT freedom of movement. Level scaling would have allowed that, making room for more options. That's an argument.
Now for if that "would" have worked better - for your play style probably not, for mine yes. If that "would" have made the game itself better, is again just opinion.
A fact is, that from over 3 million Skyrim users on PC, only around 60k found level scaling so off, that they downloaded a mod (Requiem) to change it. On the other hand, over 600k preferred Skyrim Redone which leaves level scaling and focuses on rework / adding to the perk system.
60k for no level scaling vs 600k for the same but more of it? That's a argument.
Many scaled games been improved by mods? Which many?
Oblivion yes, almost all would agree that it's gotten way overboard.
Morrowind? Nope. We have to agree to disagree here. Fact is: I just tried and have a pretty hard time finding even one mod about changing level scaling for Morrowind.
Dragon Age? Found one, apparently only somewhat successful doing so mod.
Others?
For everything else and the reason why there's no mod to add level scaling to a game - check how many games actually offer modding abilities, as it is key to change that in the first place. Not so many and about none offering as much as Bethesda for their games. That's a fact.
Implying that this lack of mods adding level scaling is prove for anything, is again just opinion.
