Much like every other game out there, preorder bonuses are coming into play. These will vary by store, so pay attention. GameStop preorders get two in-game items – the Burning Band of Scorch and the Talisman of the Grand Mage. The first increases your attack, the second reduces damage. Steam preorders receive copies of both Dungeon Siege I and Dungeon Siege II – three games for the price of one, but of course, this is PC-only. Amazon orders come with the Bite of the Arakun, an in-game ring. Best Buy gets an in-game amulet, the Sacred Heart of the Legion, and Walmart preorderers get a mini-comic and strategy guide, possibly because they ran out of different kinds of jewelry to use for in-game items. (I don’t know that, but it would be my excuse.)
Looks like Steam really gets the best bonuses to me, but you’d better love your PC if you go that route.
