I mean, it'd've been cool if D&D had something closer to spell points but for memorization, so you could, indeed, memorize a small number of very powerful spells (for your level) or a few more if you only memorized 'lesser' spells. But it went with a sort of 'pyramid' affair where you got more spells of every prior level as you advanced, giving you just huge numbers of spells at higher level.Well, one of the spells was The Excellent Prismatic Spray, so...
Thus, coincidentally, briefly back on topic, you have first level wizards with 1 spell (or in 5e, 2 and recover 1 on a short rest, so 3, actually), wonder WTF they're supposed to do all day, while at 4th you have 6, like Mizirian, 7th, 10, like, IIRC, the greatest Dying Earth mages of all time, 18 spells/day at name level, and once you get a 9th level spell, 34 spells/day!
...and, then, on top of that, you'll be accumlating magic items, like 100-charge wands, or various 3/day this or that....
...yet, at the same time, in a living/naturalistic world, there will be many, many more encounters waiting out there for low-level parties to tackle than mid level, let alone name-level, and high level challenges would logically be very few and far between - the opposite of the resources/level dynamic.
