I'd thought I would share my thoughts on the 360 version of Inquisition from a technical standpoint. I have put 120 hours into Inquisition, my biggest file being 80 hours which is the one I beat the game with.
I really don't like the fact that I can't install it to the harddrive, that's the biggest compliant I have about the game besides the long load screens and no custom controller support. I really hope this is fixed in a future patch although I'm not holding my breath. I would love custom controller support, I hate having the main attack button be a trigger, I wish it was the A button and as I stand now, the only classes I can play are Rogue Archer and Mage. It's too much of a PITA using melee classes like Warrior. At least with DA2 I had a auto attack button and could play Duel Wield Rogue, can't do that with this version.
I've had 12 freezes in 120 hours (None since the patch came out, although I haven't played DAI much since beating the game) and some where it's random like walking up to a scout in the hinterlands and then it freezes, another time I talked with Josephine when I did the other option in her quest and it froze twice and I had to leave and come back to skyhold and it progressed normally. Also during Iron Bulls quest when I returned to Skyhold, it took like 30 seconds to load the area, I almost thought it froze for a second but it did load eventually and I was able to finish that quest off. I've also had long stretches where I have had no issues at all.
Graphically it's a downgrade from Xbone version but I don't think it's that big of a downgrade. Game looks fine, pop in can be annoying although that doesn't bother me. The Tutorial area has terrible lighting which makes trying to determine if your characters face looks good a PITA. At least it's better in Haven though. Hair is shiny, I don't mind it but it doesn't look the greatest. Wish we had more hair options but I think that's an engine limitation.
I feel bad for others who have had more problems then I had, I consider myself lucky that I haven't had more then random freeze issues. I'm hoping that Bioware will patch some stuff in like install to HD, I would like Custom Controller support as well but I doubt that last part is going to happen.
