Part of the challenge is overcoming the immense shortcomings of the DAO engine. I don't mind an updated look at the Redcliffe castle (I'm not someone that notices the throne room being the same in The Witcher either) or other areas we've visited, because frankly the DAO engine is antiquated and levels had to be created much more in mind of "The level size can't be too big or else."
I made a thread about the Redcliffe changes recently.
I seems strange to me that the castle isn't even in the same spot. I totally understand the reasons for a total redesign of the area for the new engine, but couldn't the landscape still be similar in layout? In DAO facing the beach, the castle is on a cliff to the left, high up above the town, where now it appears to be on the right and at water level, just beside the lake.
If it is supposed to be a rebuilt castle (in 10 years but lets hand wave that) are the ruins of the old castle in the game on the cliff to the left still? Or is it a total re-imagining of the area (as I suspect)? I suspect the design of DAI Redcliffe has more to do with facilitating DAI gameplay that trying to show a ten year change to an existing DAO town.
I ask because I'm fond of the occasional bit of nostalgia. I'd have liked to see Lothering, in DA2 but instead we got a barren wasteland. It seems like the Bioware artists prefer to totally redesign areas from previous games rather than trying to keep a consistent layout between games (The ME23 Citadel case in point).
Anyway I'm looking forward to seeing Orzimmar (if it is in game) but I'd imagine the layout will be completely different to suit the new game.
