It's just my opinion, but, DA:O felt more alive in both mechanics/fighting, storytelling and intensity than did any of the Elder Scrolls series. In terms of exploration, elder scrolls for sure, and it'd be a stretch to claim DA had more invested in story for each particular location.. But that's it, DA:O did for me.. No other DA did.
SO it was a fair comparison, at least to me, between comaring DA:O with Elder Scrolls, or Bioware versus Bethesda, and the further DA comes, the further it goes away from that comparison, being that Bethesda vastly comes out ahead in terms of single player (Mechanics/Story/Settings).
Unrelated to the above statements about Bioware V Bethesda.. But just thought about it..
I somehow had the impression we'd have something to do with The Deep Roads, more than maybe two quests, but we did not. Nor did we take a visit to Orzimmar. It even felt like they blew up the temple of sacred ashes to avoid ever having to worry about it again design wise. Prologue, starting quests for each race/background would have been nicer IMO with the four races, than being given a text with your 'background' and the only background that really seems to popup later are warboard missions.
One of the things that made Origins stand out for me versus other single player rpgs was how race affected your game play or overall story. Like dwarf commoner versus royalty, different short scenarios and the like. Games like skyrim just give you the the nameless prisoner role. So, yeah.. I don't know if they'll ever make another Origins like game for Bioware that can stand up to Bethesda's ES series.
