Are you serious? I don't think it's any longer than ME. Even if you chase down every single side quest, it's still only 60, maybe 70 hours.
Of course, I suppose you could complete the main ME storyline in only about 20 hours or so. But what's the fun in that?
Checked my ME save file, says just a bit over 30 hours, albeit that's only one playthrough up to level 45, and I don't believe I was being meticulous in completing every sidequest either (only because almost
all of them were the same land, shoot, loot formula).
That's compared with the 65 hours my DA:O save file says, something I haven't seen outside of my Fallout3 save games. So yes, DA:O is becoming longer than ME for me. Also it could be due to the emerging mod community that DA:O has, compared with no mods for ME even though it screamed for it.
Well I just bit the hype bullet and pre-ordered the game on Steam, it's sitting nice and pretty just waiting to be preloaded...funny, I'm usually very disciplined about waiting for reviews, but something about this just forced me over the edge.
