Dragon Age has much more to offer. And it has a wider market appeal.
I know what you mean. I've clocked over 28 hours of gameplay and I've only had it since late last week. Its already my 6th most played game according to Raptr and Im not even close to finishing the main quest or side activities. Its been forever since I got this hooked on a game. Im actually scared (in a good way) of another playthrough because of just how long it takes to do everything XD.
As to the OP DA:I has far more moving parts (things to judge) than bayonetta so the .2 meta difference doesnt mean much. Bayonetta 2 simply doesn't have the same amount of scope or content as DA:I and it would choke if it did. I dont own Bayonetta 2 but I do have the demo, its good but not even close to the same level of quality or polish as DA in regards to story, audio, graphics and definately story. The gameplay is diffrent but I much prefer DAI party based combat which looks and feels fantastic when you unlock great active and passive techniques for all your party members. The game also has so many random but awesome distractions like horse races (true story), asteriums, shard collection, operations, judgements, upgrades, requisitions and claiming keeps and landmarks. There's just so much to do and NONE of it is boring.
Its really good, surprisingly good given the scope of it all. This is what happens when talented developers like Bioware arent rushed by their publishers, I guess they learnt from DAII, Ubisoft should pay attention.
