I agree with everything Havant just said - I too have completed the game several times, plus the small fact that I wrote the DA review in 360 at the time.
Oblivion is great, but it's precisely the lack of focus which you seem to consider a plus point that edges DA slightly over its head for me. DA has a resoundingly superior narrative with far fewer places to go, admittedly, but as a result far less dead time, less identikit voices and less bloomin' cat-people.
I lost count of the hours I spent just wandering aimlessly in Oblivion, attempting to figure out how to get to some burrowed-away spot set into the side of a mountain, places where in an attempt to reach, my character was able to walk up slightly steep bits of hill, just not the slightly steeper bits with the invisible walls. Is this true freedom? Would a game featuring an infinite carpark to explore be any better for it? No, it's just a car park; it has a couple of Fiat Uno's, a Pay & Display machine and a shopping trolley.
On the subject of scores, I like the five star system. As has been pointed out earlier on in this thread, it causes people to read the words and to be honest, if I could truly have my way, I'd do away with scores altogether. If our text doesn't at least help our readers a little in deciding whether game X is for them then, let's be frank here, we're shite at our jobs.
I don't know if you noticed, but the 'Average' score no longer exists - check the opening reviews spread in any of the last two issues. This means there is absolutely no way to sit on the fence. Can't think of any other mag that does that, but it's been designed to save you any and all banal 'Mixed bag' type bollocks and to force our writers to have to go one way or the other.
We try to put enough personality into each article that you understand what kind of person each of the writers is and can either identify with them or not, but everything you need should be there.
