I'm getting tempted to make a second character now, but I'm only level 38 and I want to finish the Thieves Guild and Imperial Legion questline. I also started the College of Winterhold and then forgot all about it. I have so much on my plate I can't help but get distracted by other quests which seem more fun.
At the moment I'm running errands for the Imperial Legion, taking forts and such, it's a lot of fun I have to say. The battles are awesome and I hope there are quite a lot of them, it's a good way of increasing my Block and One-Handed.
Speaking of which, I got to 100 Sneak legitimately and got the final perk though I have yet to use it. I have to say, silent rolling is very useful when you only have a limited window of opportunity to sneak behind someone, it's basically sprinting in sneak mode. Also I often don't even need to go into sneak mode, especially if I'm looting someone's house while they sleep, they never hear me when I run around and knock all their stuff over.
I can't help but sneak on pretty much any character I do, whether it be on Skyrim, Oblivion or even Fallout 3. I loved sneaking around Raider camps with a Silenced 10mm Pistol and killing all of them without them even knowing I was there in the first place.
Also, handy tip in case anybody is confused like I was as to how to move items, you hold down the A button (on xbox, X on PS3 and probably SPACE on PC), it works pretty much the same as Fallout 3, maybe a little less OTT though, but definitely better than Oblivion where you could hardly move a body. It's also something you need to know if you want to get a bonus from one of the Dark Brotherhood quests when you're required to move a body out of sight. I'm happy they've still got it (I thought they removed it), I love making battle scenes look awesome by putting bodies all around, yeah I know I'm weird but it's pretty fun.
Oh yeah, and to the person who asked about Dragons staying after you finish the main questline, they're still there, I assume they're a bit rarer to encounter but they might not be, I've only fought one since.
Another thing, is anyone else overstocked on Dragon Souls? When I first got the game I always had a Word of Power but no Soul to unlock it, now I have 15 dragon souls and no Words of Power to unlock. It's not a big deal because they don't exactly weigh anything but I would still prefer to have some use for all of them.
