Just a couple of questions from me,
Does the game feel more like fallout 3, or like new vegas?
How does the sandbox part feel, were you able to go off exploring immediately or does the game feel like it's leading you by the hand on a more linear path?
The game feels more like Fallout than New Vegas, without a doubt. This is a good thing imo.
Oh...it really is a sandbox. In fact when I start over I'm going to go a completely different route at the start. Pretty much imo they kind of guide you to go through Riverwood and do those quests first as well as Whiterun. I think they're two town that are made for a starting character.
That said though you can basically high tail it to whiterun then take a carriage to any of the cities and "Start" your adventure there. Or, just make a left turn and run into the forest. Totally open ended after the linear first 20 mins or so.
