A little late into this conversation, but I am 322 hours into Valheim and still counting. I finished the main content about 150-160 hours in, and then I started playing with mods (such as the EpicLoot mod). Running vRoid models to replace the characters, a ton of mods to improve the quality of life.
Definitely agree with the addiction comments though. I was playing quite frequently at the beginning. Not so much that my life/work suffered, but I definitely slacked on building my side-business (until I got hit with a flood of requests from clients, and then a bunch of new clients found me to add to that flood). Now I'm back to reasonable levels of Valheim and unreasonable levels of work...haha.
