I'll start since I'm the OP:
*Replayability - There's tons of stuff to do in Skyrim and it's more fun doing them on different chars than doing everything in the game in one playtrough. There's also several ways to play which can only be explored by doing multiple chars.
*Exploring - Skyrim really excells at this aspect. I've yet do find any 2011-2012 game that has a rich world as Skyrim. I also love that it's seamless (well mostly) and that I am able to explore every region whenever I want. Level locked zones can never compare to Skyrims openeness, even though of course leveled zones have benefits as well
*Tons of lore - By reading books and talking to interesting NPC's we can learn very much about the world and this widens my interest of clearing caves or doing quests or generally just walking around. We can find monuments and other points of interests like the Moonforge- it's not very usefull but very interesting and immersive.
*Freedom of birthsign - With the standing stones we're not bound to a specific Sign for the rest of the game, which allows for more experimenting in tyring out those that seem to be bad - they're still bad but at least now I've tried them on a high-level as well, not just trying them outside of Prison and then reloading Oblivion's Prisoner-save.
Please keep this thread free of negative critcism - this is a thread for praising Skyrim.
