Er, nope. This argument doesn't work. If I find a cool gun - that's a worthwhile pickup / reward, even though I have to also find ammo for it.
If I find a cool sword that will break after a few minutes use, that's a minor reward at best.
Swords = ammo in BotW.
There are so many weapons all the time, and Jim has went to great lengths to make sure to make his point in the video, by playing the game really really bad.
Watching the video without sound:
1. He doesn't pick up weapons from the ground during the fights unless it's a really bad weapon, like a wooden stick.
2. When a weapon breaks, he selects a old (bad) weapon from his inventory, rather than picking up a better one from the ground. In the sequence starting at 1:12, he doesn't pick up the Traveler's Claymore (attack damage 11), instead he selects a spear with attack damage 3 from his inventory. For example. Same in the sequence at 2:00.
3. He fights with axes (used to cut down trees) and sledgehammers (used for mining)
4. When the damage warning comes, he never throws the weapon at the enemy for an extra damage attack and pushback.
5. In the sequence starting at 3:11, there are multiple weapons available to him on the ground. He doesn't take anyone of them when he passes them. Since he never takes new weapons from the ground, he only have 4 (!) weapons left in the inventory at 3:40.
6. In the sequence that starts at 4:22, he has a weapon inventory that is unrealistically bad at that stage in the game (after the Great Plateau). He basically only have a few weapons that are available at the very start of the game + a cleaning mop.
7. Hitting a weapon against a shield or other hard material will obviously damage the weapon. Yet, he continues to hit the bokoblins on the shields?
I'm actually surprised that he didn't included footage of mining minerals with a sword. That will break the sword in notime.
