I don't think you can zoom out to Infinity Engine levels on the console, but otherwise it's basically the same. Pause, issue commands (which is a radial on the console, so have fun with that), un-pause, repeat. Positioning is going to be a pain, but I believe the console version has less enemies overall and some encounters were redesigned/made easier to compensate for the gimped controls and perspective. 100 hours with all the DLC maybe. And if you re-load saves to see how some decisions can play out.
Origins DLC:
Stone Prisoner is essential because it adds Shale (the Golem).
Warden's Keep is good for the stash and the mission is OK. You also get some abilities from it, but I don't remember using them all that much.
Ostagar is short and kinda crap. Only get it if you find yourself caring about the story, but I wouldn't bother either way.
Awakening is an Expansion and is necessary. Without it, you can't fully appreciate how Anders' character was absolutely butchered in DA2. But it's also pretty much more DA:O, so if you find yourself liking it... Don't expect the plot to matter though.
Darkspawn Chronicles is shit, don't bother.
Leliana's Song is OK, but I found her irritating. Flip a coin.
Golems of Amgarrak expands Shale's story a bit. If you're going to get Stone Prisoner (which you should), get this as well.
With Hunt is OK. Shit ending though.
Dragon Age 2 might as well have been an ARPG. There's a boss fight at the end of Act 1 and one optional fight that requires you to use your brain, otherwise it's very easy. If you up the difficulty the hordes of enemies and reinforcements will be even more irritating, so you're fucked either way.
Aveline, Varric and Act 2 (the Qunari Arc) are the highlight and it might be worth playing for that at least, but it's otherwise crap that destroys the few good ideas it had with comic book/anime bullshit and doesn't meaningfully improve on DA:O. It is likely the better console experience, but I don't think it will matter much in the end. Play a mage for an especially
experience. It's much shorter than DA:O despite their very obvious attempts to stretch the play-time.
DA2 DLC:
The Exiled Prince adds a character. He's a boring, "lawful good" archer that adds nothing to the story. Not that I can recall, anyway.
Black Emporium. Trinkets and don't remember what else. Respec? Re-doing your face? Not sure.
Dunno about the others because I didn't play them.
Have fun, I guess?
