A note though before we start. I shall be comparing this game a lot with Baldur's Gate 2 considering the developers at Bioware considered it the "spiritual successor" of it.
The plot (thickens)
Well... truth be told, it does not. There's nothing that makes the main plot in any way surprising. It's simple and straight forward and while the game offers a lot of choices to go through with it, I didn't find the patience to go through all of the possible endings. It is an enticing story, but nothing more. (I could go into great detail about it, but I fear spoilers). If I were to rate it, I'd give it an 8, for good writing, but not further up on accounts of predictability and straightforwardness.
The Characters (maybe fonts?)
Well well well... to tell the truth, it has been an extremely long while since I've seen such well made characters in any game. All of them are memorable and fun and the voice acting is brilliant. There are romance points in the game with more than one person (seems that they learned their lesson from Neverwinter Nights 2) and all of those that I found were unique and interesting in their own way. Also the game tackles the gay (male, and I would suspect female - I didn't try that out) relationships that most other games would not touch, and I sincerely applaud them for making Zevran a very likeable character. I'd not put him past reaching the epicness of Boo. If I had to rate it I think a 10 would be sufficient, because the characters border perfection.
The Graphics (are eye candy)
To say that a game has good graphics these days is like saying it comes in a box. We have achieved a good place in time when the eye candy of a game is really important, but considering all that's out there, all the sources of inspiration etc, etc, etc, you'd have to be a blind wombat not to be able to get it right. What we can talk about is how well optimized the game is, and to tell the truth, I'm not really sure. My computer had a few hitches here and there on almost full graphics but overall it was a pleasant experience so 9 would be sufficient.
The soundtrack (chuuu chuuu!)
To put it simply... it is great... at a point one of the characters sings and I loaded the game up 3 times just to hear that... It was that awesome...
The gameplay (tossing and turning)
This is the point where I take out my PC is the master race hat and wave my flag around. This game has the same problem as all the games that are made with gaming consoles in on the prime plane. You can clearly tell when a game has that in mind and you can see it clearly in Dragon Age origins. The controls are simple enough, and the interface is okay, but the way the game works, simply puts me a bit off it. It's a certain je ne sais quoi that the game has, as opposed to, say The Witcher which is a PC exclusive title. Areas are relatively small and have very little branches or liberty of movement... I once got killed by a monster because the character I was controlling got caught in a twig. I kid you not. That's not the sort of collision detection that a game in this day and age should have. But enough of my ranting... while the game smells of console like socks in a gym bag, it doesn't really ruin the experience, and then again there are some out there who are not PC master racists like myself, so I find it unfair to give the game less than 8.
Replayability (dragon is replayable)
The game has 5 origin stories which are all well written and it is said that the world reacts to you depending on your origin. The differences as far as I played in the main story, are minor concerning NPCs but enough to warrant a replay out of the more dedicated fans... or maybe myself when I'll be bored again. Also, being the experienced gamer that I am, I think the almost a week of constant playing says much about the game's length.
All in all it's a good game, and I compared it to Baldur's Gate 2 far less than I expected to. It definitely deserves a buying but the spiritual or otherwise successor of Baldur's Gate 2, Dragon Age : Origins is not.
