Everything I've seen from thie e3 conference so far has made me think this zelda game looks oddly familiar and that's because it has a lot of mechanics and similarities to other games so it's kind of a weird mish-mash of a bunch of games and let me tell ya the majority of them are good so I briefly came up with a list and reasons why I think this and for the record this isn't a bad thing I actually really like the look of the game and I'm glad that it's so similar because all these things together is a really good combination as seen by all the gameplay of the demo so far.
So without further ado..
Shadow of the collosus - Heavy use of bow, horseback riding HUGE expansive world
ASSASSins creed - Mountain parkour
Portal - Sheikah thing let's you pick up things
Dark Souls - Parrying, Rolling, Armour, Weapons, Lighting fires etc.
Every survival game EVER - Inventory that carries supplies that you use for y'know survival
Zelda - It's a zelda game after all
Monster Hunter - CLimbing walls mechanic is very similar you even have a stamina bar
The elder scrolls: Skyrim - Huge open world and a huge selection of side quests
If you can find any more please go ahead and share please because I feel like this list could go a bit further and also don't hurt me :c
