My biggest problem with DA:O (which I enjoyed on console) was stupid shit that comes from its PC heritage. The whole affair was buggy as hell, especially when you get to the DLC. I defy anyone to play Awakenings all the way through without the Rosetta Stone of Wikia to help you through all the bullshit.
Oops, Sigrun's companion quest won't start if you've already done the unrelated "Law and Order" quest (actually, L&O messes up several things unless you do it at the end, which is dumb because it's the very first thing you're presented with the first time you step into the game's only city).
Oops, Justice and Sigrun's approval systems are bugged and don't work if you've already done the unrelated Blight Orphans quests.
Oops, Sigrun doesn't become a Grey Warden unless you leave the dungeon early, go back to Vigil's Keep and let her join, then return to the dungeon and finish. Even though she doesn't want to become a grey Warden until you finish the dungeon.
Oops, my player character suddenly has an arm sticking out like he's holding a sword. Nobody knows what triggers this, but it'll be that way for the rest of the game, unless I go back to an earlier save.
Oops, "Bombs Away" can't be finished for no goddamned reason.
Oops, several other quests can't be finished, also for no reason.
Oops, people constantly move their lips with no sound (which you're then supposed to respond to, without knowing what they said).
Oops, when you enter the Silverite Mine, there's a 50/50 change all your gear disappears forever. If you save afterwards, you've broken your playthrough. You won't know this until twenty minutes after the stuff disappears, because in the story you get captured and stripped of your goods. If the bug happens, you never get it back.
Oops, unless you've uninstalled the Warden's Keep DLC, the best Armor in the game can't be seen. Oh, Wade will still make it for you, but you just can't see it, even when it's equipped.
Oops, the same statement applies to the best sword in the game. By the way, on PS3, the only way to uninstall Warden's Keep is to uninstall everything, then reinstall everything except Warden's Keep.
I could go on and on. This list could easily be three times as long. AND, this is all stuff that's wrong with Awakenings. Don't even get me started on how often Darkspawn Chronicles crashes. Or how Witch Hunt has the cruelest bug of all at the very end, which, if it happens, requires you to replay ALL 20+ hours of all the DLC again (if you still care enough to fix it).
So why do I blame PC gaming for this bullshit? Because the vast majority of these issues have a fix of some kind, if you delete a .dll or copy/paste an .exe, or install somebody's mod. In most cases, Bioware figured said fix was good enough, and the console audience could go fuck themselves. Ironically, this is the kind of PC gaming stupidity that has always kept me on consoles. You put in the game and it works. Bioware comes from a PC background where they expect consumers to research how to fix their games. A "patch it later" mentality.
So if DA2 is catered more toward 360/PS3, I'm totally on board. Especially if that refers to the level of compatibility.
