You can beat it whenever you want, it's still a good 70hrs
After nearly 70 hours, i think I'm gonna stop playing and I've only done one dungeon :/ i just don't have the interest anymore. Could just go to Hyrule castle now and at least see the ending i suppose, but in terms of exploring the rest of the map and finishing the other dungeons, i don't know if i have it in me.
Turned off after half an hour this morning, just don't have it in me atm, which is sad. Might try and come back in a few months.
Edit - like this basically. Im burnt out on it. I'm actually looking forward to just dicking about in Lego city on Friday.
I can't get over games like witcher3 for 20hours tbh
Have fun on lego city
