Day 22 Update: (may contain slight spoilers containing number of shrines and such but nothing major)
After reliving my youth for three weeks in this game I'm pretty much done... was a glorious ride
After work and weekends playing an unhealthy amount, most of the time in amazement, now I have little left to accomplish and can happily go back to my non-gaming life.
What a wonderful game. I really can't stress enough how much I enjoyed my time in this world. I absolutely love how you can do whatever you like in whatever order you like, go wherever you want whenever you want. There is no wrong way to play because there is no correct path to take. The game starts on a specific piece of land that you must clear before the rest of the world opens up to you but after those first couple hours you could literally go and fight the final boss of the game immediately. Granted it would be difficult to make your way to him and you wouldn't stand much of a chance in the battle but I would guess it's been done
General:
Amount of time put in... dunno and don't want to. Well over 100 hours if I had to guess. VAST majority of it was spent exploring places I'd not been before... the world is just enormous.
Everyone's path will be different. Mine, I started off traveling east, about halfway to the coast I started veering north. Upon reaching the eastern base of Death Mountain I turned east and explored the rest of the world in a general clockwise direction so DM itself was my final new exploration before the castle.
I never used horses to cover ground and feel those who do have got to be missing a literal shit-ton of the game. I was always exploring vertically which horses just can't do. Only two horses I ever registered were two special quest horses.
I actually didn't mean to beat the game yesterday... decided I wanted to enter the castle and climb to the very top and on my way back down figured I'd stop in to have a look at Ganon. Ended up beating him. Continuing after winning the game takes you back to your last pre-battle save as the world would be a monster-free place with Ganon gone though you do get a star next to your save files as an "I beat the game" icon.
After winning the game you get a completion percentage shown on your map. Mine is 37.05% with all but 5% of that being unfound Korok seeds.
Shrines:
There are 120 of them. 78 "normal" shrines and 42 quest shrines. Found 113 of them through normal game play/exploration. After beating the game I looked at an online map to get the general location of the other seven as the world is just far too fucking big to even attempt finding them. Needed the assistance on finding three of the quest shrines and four of the they-can-be-anywhere variety. By far and away the two best shrines in the game are in the extreme northeast and southeast corners.
Side Quests:
There are 76 of them. Completed 59 through normal play and again consulted Google on locating the remaining 17 as they would be extraordinarily harder to find than the shrines as some are very random in that it's not just finding the right person to talk to but you have to happen to find them at a specific time of day and location (fuck you firefly bitch).
Korok Seeds:
Fuck those things. There are 900 of them. I found 176 during my time exploring and have no interest in tracking down even one more, much less 724 of them. I said it once but I'm gonna say it again, fuck those things.
All in all I had a fucking blast playing, easily takes over the #1 slot of best game ever on my list. If I wanted to continue playing there is still plenty left I could do in Koroks, maxing armors, compendium, etc but thank God my OCD only required finishing off the Shrines and side quests. I am very happy this game was brought to my attention... and now I am happy to be done
