Been playing this in fits and starts since I got it at launch last March (on Wii U).
With a full-time job and two small children, my personal recreation time is limited, but I usually get in an hour or two of Zelda in a given week.
In the past 10 months, I have beaten all 120 shrines and all 4 Divine Beasts, recovered all memories, and defeated Ganon just to see the ending. I've been working on fully expanding my inventory (darn Korok seeds - only one more shield slot to go!), and collecting and upgrading all of the armor (most sets I have are levels 2-3, but my Soldier's Armor is maxed out.)
I've completed nearly all side quests - there might be a couple minor ones out there I haven't found yet, but I've completed every quest and quest chain I've come across, including all DLC side quests except for the two main ones: Trial of the Sword and Champions' Ballad.
And those two are what I will probably do next.
How hard is the Trial of the Sword? Is it doable for someone of average combat skill (keeping in mind I have a full 30 heart containers to work with)? I'm ok but not great at combat - generally go through several meals when fighting Lynels, even when using very strong armor and good weapons.
