Been playing this game at least a month now and still hooked. I started off as a Dark Elf who's currently about Level 27, who I mostly focused in Magicka and duel wielding. Did the main quest mainly so I beat it within a week and then started on other quests. Currently doing the Dark Brotherhood turning him into a stealth character. His sneak is already up pretty high and it's awesome going into dungeons and picking them off one by one with my bow and arrow. Kinda regret making him a Vampire now since I have to feed but it's not too hard to do, would be nice if I didn't need to do it so frequently though.
I also started a new character on another account who is a level 25 Orc warrior. I leveled him up a shitload faster than my Dark Elf, I started focusing on my blacksmithing earlier than the Dark Elf and it's already at 91, just from making Iron Daggers. Also used the speech glitch to get my speech to 100 after I was so frustrated with always selling things for a fraction of the price. Doing the companion quests with this guy so he's now a Werewolf but I've only used it once.
In short I am loving this game. Even more after starting my second character. My experience is completely different every time. On my second game, I decided to go straight to Whiterun after escaping Helgen, couldn't be fucked with following that guy to Riverwood. As I got to Whiterun a giant was attacking the farm so I helped them kill it and they asked me to join the companions! I nearly had an orgasm when some thugs jumped me and after killing them I discovered they were hired to get me.
In all my years of gaming I've never played anything so deep as this. A game where people will comment on pretty much everything you do, praise you, or hold grudges against you... Skyrim is amazing.
