Dragon Age Origins questions.?

I am thinking about getting Dragon Age Origins for my xbox 360. I would like to know if anybody recommends it, if not what is wrong with it. Also I would like to know the general storyline and how long the game is. What is the combat system like, I have seen videos with four characters and you could take over any of them, pause the game while selecting a number of attacks, and then switch characters while the game is paused, which made it look like more of a strategy then a RPG. Lastly, I would like to know about the add on pack: Awakening.

Thank you if you post answers to my questions.Dragon Age Origins questions.?
I personally think it's a great buy. The storyline changes in the beginning a bit, when you choose your origin, (Human Noble, Mage, City Elf, Dalish Elf, Dwarf Noble, Dwarf Commoner,) but the story is the same in general. Deformed creatures called "Darkspawn" are invading Ferelden, and it's up to you to stop them. They are led by a dangerous creature called The Arch Demon. You become a Grey Warden, a society of the World's greatest warriors who are swarn to protect the world when complete destruction is imminent. The combat system is easy to use. You CAN pause and scroll through your abilities, but you can assign 8 to the X, Y, B, A buttons for easy use. (8 abilities should be enough to get you through most fights.) Awakening lets you continue after beating the game. More quests, items, and such, and allows for free roam if you want to keep playing. (I think you can also start a new character at Level 20 for Awakening.) Hope this helps.Dragon Age Origins questions.?
Yes, definitely get it!

the game isn't like a typical RPG, but it's not meant to be

i would like to say that the PC version is 10x better than the 360 version (better visuals, controls, etc.) and since the game isn't online it doesn't matter.

however, there was a price drop for the 360 version.
