the problem is that you know what all items do and whats next.
You played the game and passed tutorials and trials, you crossed the line of mastery and now its just you going back for bigger challenge.
While this is true for OoT / ALttP randomizers, I think if an entire game were designed around this then it would be fine. Some things would probably need to be simplified to make a first playthrough enjoyable; for example, in OoT randomizer there's a bunch of settings to turn off the Door of Time, open up the forest from the start, etc. and these are all byproducts of it being built off of an entirely linear-focused game. When designing something like this from scratch those kind of pitfalls could be avoided. I mean, we already have roguelikes which in addition to giving you completely random weapons, randomize the layouts of locations. I don't think it would be too challenging.
I was kinda frustrated for the first hours of oot because it was all about slingshot and nuts, cant imagine whats gonna happen to player who plays most of the game without shield for example.
Well, the thing is that OoT is a really easy game already so it kinda lends itself to this. The challenge in playing most of the game without a shield isn't that it's hard without a shield, it's finding out what you can and can't do without the shield. It forces you to explore the world more than you normally would. That's the whole appeal of randomizers too me which is why I think it would make an interesting original concept.
