I took off early yesterday from work so I could play when DA: O unlocked on Steam. Bought the digital collectors edition preorder some time ago. To preface this I am a huge fan of Bioware and single player RPG games, I have played pretty much every Bioware game up until now and this in my opinion is their best.
I played for maybe 6 hours last night and was thoroughly enthralled with the story line. Graphics wise no it is not the most groundbreaking graphics engine ever used but it looks darn good, and when it breaks into an ingame cut scene you really get sucked in. I had to force myself not to call in sick today because I wanted to stay home and play. I ran into no bugs in my playtime so far. DLC is handled well and it ran crash free the entire time I played, I only restarted the game after some DLC finished downloading it dropped me a message in game telling me it was done and for it to work I needed to save and restart.
I found myself turning down the TV and telling my wife to stop yacking my ear off so I could hear the ingame dialogue something I rarely do, usually I pay more attention to the TV when I am gaming. My wife I always tell to shoosh
The in party banter between the characters is great, my party members even make comments to Dog and he replies with growls and barks depending on his mood.
The only thing I don't like so far is the new system they have developed, I have always been comfortable with the D&D rule set in games, this one is just foreign enough to make things sort of rough feeling. I don't mean the system itself is bad, I mean I am just not comfortable with it yet, I am sure it will pass after I understand the mechanics a bit more. The system is interesting but after 6 hours I already feel like I hosed up my character with my skill and point spending through the levels. It will take a bit or research for me to get a good feel for the mechanics so I can shake the "I screwed up my character" feeling.
Unless something horrible happens game wise in the next few days like the story goes to crap or some crazy technical issue pops up this game could easily be the best single player RPG I have ever played.
