Well, I bought it . . . although I'd buy almost anything made by Stardock - and have. But as far as DLC goes, it's not particularly exciting.
Will there be more DLC? Will it be better? I'd love to see something that adds more spells, or something that makes the combat at least as good as MoM (and maybe even AoW, because it's one of the weak points), or adds in Titans, or my personal favorite, the Item Forge.
Let's just put it this way - as I've played the game, the one thing I've never said is, hey, I'd really like more maps. But I've cursed the unimpressive combat, rued the small number of spells, and sneered at the minimal selection of magic items.
