Because I recently had Skyrim experience, which was surprisingly good, I just wanted to add some things.
The only type of that leveling that could work for newer type of real time Fallout games is sneak skill, or healing or even survival.
But anything else is impossible. Because Skyrim is in general action RPG, throw Assassins Creed 2 and add RPG elements to it. It's good, yeah, for a fantasy game again. But imagine firing .50cal Anti-Materiel bullet, surviving it and doing the same thing again to gain more levels. Problems? Yeah, because it wrecks you apart you would have to be going up 15 levels, which would add harder opponents if there was level scaling. Or try letting Super Mutant hit you 100 times in the head, add more skill points to armor. Hurrah! Then get killed by radscorpion poison because he got to level 150...
The game mechanics are inherently different. It's impossible to change it to the core. Else we would get 1000 tons of ammo in Wasteland, which is very stupid. On the other hand, I can go and do smithing and craft a sword or an arrow. But I can't quite do the same thing with a full caliber weapon if I was born in a world where I wouldn't know what the hell toilet paper is.
Also whoever wrote that IGN text seems to have forgotten Gothic 3. Patched game can par with Skyrim easily with the massiveness. And it used a rather different RPG system, which was good in the end, which was transferred to Risen. Their type of a game, not "bought licence haxoor i best rule, make it fun" type. Again, I specify G3 patched version, official product was a fail because of the bugs.
But it's not like everything was so spectacular we have never seen it anywhere like in Skyrim. Beth just have their own way. Works for them, we know it works for TES games, but don't force it on others.
I still thank the good lord or whatever is out there for Obsidian and FNV. And you can see how Fallout 3 was easily affected with "the Scrolls syndrome". FO3 had mostly filler perks, made you a god walking machine in one minute of play and bored the shit out of the rest. FNV was careful planing, using Van Buren as a balance pillar.
The experiment to merge Fallout and Scrolls leveling simply failed. Problem is, Bethesda is going to continue using it this way. They are almost the same as Team17, thickheaded one way street...
