Just reaffirming Dragon Age: Origins as my game of the year. And that is the Xbox 360 version!
Just finished it not 5 minutes ago and WOW. I actually enjoyed the ending and the way it presented text with images so that it could reflect on how you personally affected the world. Looking forward to a second playthrough to do things differently.
 
That final battle was crazy. A dragon is enough, but then it starts sending other troops at you as well. During that contest Wynne died, no matter how hard I tried to use taunt and war cry to get them away from her, some shrieks killed her. That was pretty bad. Her being my main healer and the only one with 'revive'. Sometime later Alistair died. Suffice to say, I couldn't bring him back. 
 
The Archdemon was pretty weak at this point, and my army troops were helping pretty well in distracting it. My main character (Lvl 19 Dwarf Warrior) was doing pretty well. Morrigan was now acting in support as healer and occasional attack spell (Winters Grasp and Blizzard mainly). When the Archdemon was JUST about dead. My main character died too. No more health potions. It looked almost over, after a bloody half hour or so of fighting, I would lose.
 
Please Morrigan, just survive. Her health dropped. She healed.
 
All my army troops died! The dragon has only one target left.
 
Check radial menu. Holy shit! Human warriors! Call those bad boys!
 
Thay run into the fray, distracting the dragon. Morrigan sits back. Heals self. Occasional grunt runs out she has to deal with.
 
Winters Grasp. Attack Attack Attack. Winters Grasp. Blizzard. Lyrium Potion. Repeat
 
Finally the dragon falls.
 
The relief was intense. I DID NOT want to do that again after getting so damn close.
 
Great Game
