This game has pulled away from Oblivion in many ways. The battles are more epic, the quest are more interesting, and there are battles with dragons (need I say more?). All combat is basically the same as Oblivion but instead of going into gates and having to run a gauntlet every 10 minutes you can walk around and at any given moment a dragon can fly down and initiate combat.
Of course you are given the proper tools for dispatching these dragons. With a follower behind you (which is a must if you are like me and put it on the hardest difficulty) you can take turns sharing blows, or if you go mage style like I did on my first round then you can use your companion as a tank. The companion system has been improved to the point to where you won't just feel like the companion is getting in the way. You can order them around and if you use special followers (say someone from thieves guild) you can order them to pick a lock or if they are in your way u can tell them to move.
Also with a massive civil war going on in Skyrim between two factions, you choose a side and get to freely slaughter many enemy soldiers. Truthfully there is SO MUCH content in the game and so many side quests I have spent over 100 hours and maybe reached a halfway point. Thankfully lag is reduced on this game from Bethesda (Fallout: New Vegas had horrible lag), and you will only experience a few things lagging a bit, but I didn't see this until I was deep into the game.
Overall Bethesda outdid themselves. The storyline is excellent and considering it seems like two different main storylines going at once with the dragons and the civil war, you got plenty to keep you busy.
I RARELY buy games anymore because of Gamefly, but this game is one of the few games that I proudly say that I own. With only a few minor bugs here and there, this game gets a score of 10 from me. The game seems to never end, and that in my book is always a plus!
