I’m not sure I understand what you’re referring to. If by “three tiers”, you’re talking about pre-Hard-Mode, Hard-Mode, and post-Plantera, I don’t think that falls under what is typically meant by “level scaling” (I realise you didn’t use that term specifically, but people up-thread did). Level-scaling would be if a green slime, which dies in 2-3 hits at the beginning of the game, grew stronger alongside the player such that later in the game, it would still take 2-3 hits.
I’m not saying this just to be a persnickety asshole, but instead to make the point that Terraria is so great because it doesn’t have the kind of scaling that Oblivion and many other open-world RPGs have. I love how Terraria has no qualms in repeatedly bitch-slapping you back to spawn if you insist on heading into areas you’re ill-equipped for (and the tiered progression ensures that there’s nearly always some such difficult place, even as the player levels up). I also find it interesting how the tinkerer’s bench acts as a key driver of progression by allowing you to pack more accessory function into fewer equipment slots.
That is to say that unless I’m misunderstanding you, I completely agree with your points, except that I would consider this to be an example of good progression without level-scaling
Absolutely iconic, I love it.
Anyway, since thinking of Cult of the Lamb has got that Stupendium song stuck in my head, here it is for any of you who want to share in my curse https://youtu.be/6ywXBNpc-To
