Only up to 3 though. So not too great. I would have used it to store the re-forgeable weapons from each race, but it's missing a single slot... Only reason the weapons breaking works out well is due to the limited inventory. I.e. you end up wanting weapons to break to make room for new weapons.
The funny thing is, there's plenty of issues about the game that don't even have anything to do with the weapons. This video by SuperBunnyHop puts an interesting spin on things, he's pretty much 100%ed the game and no-lifed it the first week doing like 100 hours in that time alone, so I guess any criticisms he has are as fair as they can get... and the video title is so damn accurate, also featuring tons of rhymes!
Playing yesterday, I will say it's starting to drag me down a bit. I'm no longer excited to explore the top half of the map and now I just want to get quests and stuff done. I have also found a place that lets players craft what looks to potentially be the most powerful weapons in the game (and a set of armour). Only issue is that it's expensive in both Rupees and materials. And weapon's breaking has honestly put me off from wanting to make any (i.e. permanently losing a fair amount of resources to get something temporary). I'm currently saving up materials form the armour and it seems some of the later upgrades for various pieces need some rare materials.
And I found that I suck at face to face combat. Probably the fact that I've had the sneaking armour the whole game and just snuck up behind enemies for the stealth-kills. Tried 'training' by fighting some blue moblins yesterday and I can't time dodges right, either that or the animations are way too fast for some attacks. And I'm thinking that I should defeat a Lynel before picking up the Master Sword (a small self-imposed challenge) lol. Speaking of which, I left it and dind't pick it up yet. Somewhere else spoiled it for me that the Master Sword isn't all I hoped it was.
A very late review from AngryJoe, featuring all the dressup and funny stuff, spoilers: he likes the game. Even the things that many other folks (like long term fans) didn't like. And to be fair, I must agree with him that the 'dungeons' in this game are fun. Even if short-lived. Like SuperBunnyHop, he still misses out on a ton of the bad things about the game.
And thumbs up for the rain poster above. I was doing one of those blue flame runs yesterday. Rain fell twice. Oh and it was every other minute when I was doing those rocky outcrop islands the other day (lots of climbing around). Rain does nothing positive for this game, I swear.
Edit:
Same here. I bought a whole bunch of new slots the other day. Then I got elemental 2-handed swords and tier 2 elemental staves. Now all that new inventory space vanished. I swear some enemies don't even have an elemental weakness. Only the fire/ice ones do and the lightning ones seem to be strong against everything.

It was on my way to Gerudo for my second beast that the map felt stretched and ultimately empty when this sank in. I personally don't mind the grindy stuff like collecting parts, but only if it has a purpose. Not much reason to get better gear (beyond seeing what the lvl 2 set bonus is) when you can dodge better / murder quicker.
