Dragon Age will not be anything near the insane quality and huge scope of Oblivion, but I believe it will be a great game.
Oblivion crushes every other RPG (except for it's lil brother Morrowind).
Dragon Age will hover around 90% on Metacritic. Should sell over 2.5 million on PS360 alone.
Oblivion is failure as a RPG especially with leveling system.
Hmm my level depends on main skills i chosen and enemies scale to my level- ok let's make some useless shit i'll never be using my mains.
Oh road let's keep jumping on it till i reach another city so i can level my acrobatics a bit.
Oh hill let's jump down from it it will give me boost to acrobatics and i can level up healing spell a bit.
And there's no chance for 2,5 milions on consoles if you look at polls on Bioware site majority of people voting there said they want it on pc.
