Woah. You must not be planning to buy any other game for a while haha. I'm 60 hours in and almost done with the game - just need to complete the last ~20 shrines, last memory, last Beast and a handful of sidequests. Might end up upgrading some armor to see all of the upgrade animations but I'm not feeling like material-farming for long to upgrade a whole armor set or anything like that.
Speaking of which, I wish the game did a better job of managing my sidequests. I'd like it if it kept track of a number like it does with Korok Seeds/Shrines, or if it was possible to sort them by region. They have a region subtitle underneath, but the way they're ordered on the list seems super arbitrary.
Also, can't believe how overpowered I am. The beasts' rewards are ridiculously OP, and the armor/weapons you can get turn you into a beast. Guardians and Lynels pretty much have no chance against me. I hope the DLC is super hard.
