Yep. I started a new character this weekend. I’m not done with Skyrim yet. Heck, I’m still playing vanilla Oblivion.
+1.
There are now 2 different versions of Niamh in Skyrim, and she's still in Oblivion.
Admittedly they all exist in heavily modified versions but neither I nor they are likely to get bored anytime soon...
Plenty of other things, but not bored.
