Sure and games like savage worlds are great but even they don't have level scaling. Yeah and some stats don't scale, but others do and a person with 16 advances is a lot more powerful than someone with 0. Since they went with a non-hp system anyone can handle any monster at any time, it just might be unlikely. Like I think dragons have 20 armor in savage worlds, good luck breaking that damage threshold if you aren't advanced enough and with good gear. Thing is virtually ever PNP game out there is level scaling free, the DM is making things "linear" by picking level or challenge appropriate adventures for you. If you go off the rails and try to assassinate the Archmage who runs the mageocracy 3 kingdoms over you will likely get curb stomped 1 second in on the other hand if you decide to handle some petty bandits you heard about the challenge will be small. In PNP games the challenge is usually appropriate to the challenge and the DM just makes sure the adventures that come up for you are challenge level appropriate. Usually the dragon wont magically have only a 10 toughness is a savage worlds game just because you decided to jump it at a low "level", it has 20 and your measly 2d6 attacks wont get through that unless you get really lucky with exploding damage.
And once again, what makes you capable of tackling a dragon in Savage Worlds? You don't have more HP, meaning the dragon takes you down equally fast (as in TES games, with scaling damage). Your sword deals the same damage at all levels (like in TES games, with scaling monster HP).
The difference is skills/perks/spells = edges, powers, relics. Numerical scaling is minimal, but options open up that allow you to win. People is making it sound like scaling in Skyrim (or any TES game) literally makes every confrontation a matter of trading blows. It's not like that.
Take stealth for example. Sure, monsters may scale with you, but they don't scale with your perks. You don't have the same odds of clearing a bandit forth through stealth at level 30 with 50 stealth and 5 stealth perks as you had at level 5 with 15 stealth. Even with scaling.
And that's what leveling is all about.
