Yeah, I'd say that if you've managed to at least get most of the achievements from the previous games, you shouldn't have too much trouble with this one.
I'd recommend doing all the main achievements before attempting Awakening.
Especially because it's easier to do the Devil's Hand work around without Awakening as you have to delete the DLC as well as the update for the work around to actually work.
And of course having the DH for Hard Core and Pure Survival makes those difficulties far more bearable.
It's just a shame that you have to use the damn work around in the first place.
