The best example of this is any game from Piranha bytes. Especially first Gothic was prime example. You’re such a piece of sht at the beginning that every single even the most basic creature will give you hard time killing it or will smash you with one hit in case of stronger ones.

But as you level up and get better gear things will change drastically. Even couple levels or stronger weapon will enable you to progress to new part of map, because now you’re able to finally kill the pack of wild flies guarding the passage.

Few levels later you can even go through forest without constant fear of wolf attack. And at the end you smash shadowbeasts like it’s nothing… This feels awesome and that’s what level scaling absolutely ruins.
