I would say it is videogame-y, because this particular kind of absurdity is common in MMORPGs and to a lesser extent in RPGs generally. Where level limits are stuck on things not because it makes the slightest bit of in-setting sense, but because it's there solely to balance some mechanic.
For example, see The Witcher 3, where Geralt can easily get weapons he can't wield because he is too low-level, or clothes he can't put on. It's entirely antithetical to the fiction of the setting, and purely an absurd game mechanic.
This is something D&D, and games like Elden Ring, which have a sort of D&D vibe, actually have almost always avoided. You don't need to say, level 15 to wield a vorpal sword in D&D - but it's unlikely the DM would give one to PCs below that level. Should they get it though, they will be able to use it. Likewise Elden Ring - there are weapons it's nearly impossible to get at lower levels, but if you do get them, and you have the stats to use them properly (i.e. strong enough etc.), you can use them.
