I played the Dragon Age II demo today and it was pretty awesome. In the demo, I chose to play a rogue, which meant either dual-wielding blades or bow and arrow. I chose the blades.
There are essentially 3 parts to the demo. In the first, you and a mage are fighting lots or darkspawn. This is a memory of one of your soon-to-be compatriots. Then you are with your family and escaping the burning of Lothering by the darkspawn. This leads to the formation of your party of 4 (soon to be 3), where you end up at the earlier scene, though with a bit more help. A surprise shows up to save your butt, and then there is a jump to a later scene where you have an indoor fight.
The demo is sometimes difficult, and I had to do the troll battles a couple of times, because the entire party kept getting wiped out. The graphics were good and the effects excellent. The backstab ability of the rogue is especially cool!
The demo portends good things for the not-soon-enough release of the game. Looking forward to it!
