Let me tell you right now: Justice is "that one BioWare NPC" in Dragon Age:
Origins -- Awakening. You know who I mean; how in every BioWare game
one of your party members utterly breaks out to become a bizarre and
awesome character. For the Baldur's Gate franchise, it was Minsc, the insane ranger. For Knights of the Old
Republic, it was the sociopathic assassin droid HK-47. For Mass Effect,
it was Wrex, the talking dinosaur wielding a shotgun, and for Mass Effect 2,
it seems to be Mordin, the singing scientist. For the original Dragon Age:
Origins, it was the curious golem Shale, and so for Awakening, it's
definitely the
ghost-from-another-dimension-trapped-within-a-medieval-badass's-body,
Justice.
Besides introducing another great character to the Short List of
Badass BioWare NPCs, Awakening adds five other party members (two per
class total, and only one is a returning character from Origins); an
increased level cap; several skills, specializations, and talents for
said level cap; additional items (and tiers that indicate quality;
Origins stopped at Tier 7, and you can now have Tier 9 items); new enemy
types (including monsters that look like a cross between giant spiders
and the monsters from Critters);
and a 20-25 hour campaign. It's basically the Dragon Age 1.5 that you
knew you'd be getting, as opposed to a, "you expected Dragon Age 2 but
actually get Dragon Age 1.5" situation.
