I play slowly. 255 hours since I purchased the game in - I guess I don't know. But sometime in 2013, I believe. I have 3 kids and I'm part of an intentional community. I have on average 3 hours of gaming time per week.
But, it's pretty wonderful having the same modlist all this time. I'm now level 51. I have completed the Dragonborn DLC, and I'm midway through Dawnguard. On the main quest I haven't talked to Delphine yet. I've maxed out the trees for Blocking, Heavy Armor, Smithing and One Handed. Alchemy and Enchantment are next - halfway through them, I'd say.
The pacing is working well for me. I still run into things that can kick my ass. A lot of encounters are still challenging. I still feel like I'm encountering new content.
533 hours into Oblivion. But I didn't finish the main quest until after I'd purchased Skyrim. And I never put this many hours into one modlist.
I've become a firm Skyrim favoritist.
Thanks, modders!
