The only reason I had played Dragon Age Origins, DAO was because my brother told me it was close to Witcher 2 (I was going through withdrawals lol)
And depending on the choice you made with your character would alter the way the story played out.
I had chosen to start off as a female noble and loved my background story. It was something relate-able (not that something like that will happen to my family since the US doesn't have any nobles, but if it was I could relate to the choices I had made in game)
So there can't help but to bit a bit of an emotional connection to the story that is play out.
The premise is that you become a Warden, a tight knit group created with the sole purpose of defeating the darkspawn and due to unfortunate circumstances you and another warden named Alistair are the only wardens to protect this part of the land along with a mage, Morrigan.
From there your choice play and cause and effect, Thus something is always on the line making the decisions a bit more difficult. Well for me it did, maybe cause I'm a softy and want to help everyone.
You are able to gain additional party members by recruiting them when you meet them in the story.
You are able to have romantic relationships with all options available, you know fem+ male, fem+fem, male+male so something for everyone. but I do believe some characters are bound to the orientation they are, EX Alistair is a straight dude so he will have romance options for female wardens only (even thought I did hear there is a way for male +male with him , you google that)
Now there is a clear FAST LANE to get from beginning to end of the game however it's not restricted you can take on many of the side quest to make your gaming experience all the more better.
As for endings, there are various ending that can occur depending on your decisions which is why I loved DAO, It made me want to play again to see the other endings.
In the end, my female warden became Queen of Ferelden along side King Alistair and I was content with that.
I LOVE THIS GAME
Fucking loved it, if you can buy ultimate edition on steam to get the most out of the story.
NOTE: awakening and other DLC don't really do much, it might be easier saving the 15 dollars per DLC( if you didn't buy the ultimate editions) and just youtube the story.
- Game rated MATURE!
I can't wait for Dragon Age: Inquisition I heard that it will pull background from DAO but not your direct character. ( I didn't bother to play Dragon age 2 since I really didn't care for what I read on it)
If you didn't play DAO but want to customize your world for DAI then I think you can still do that by going to dragonagekeep, google it.
