I'm not normally a big fan of dungeon crawlers (I tend to get bored with RPGs focused entirely on combat / loot; particularly with "blobber" style FP combat that most crawlers have). However, I am very much looking forward to this game because it will have AoD's excellent, tactical turn-based combat and character building system. Also, from the sound of things, the game will feature about 50 large scale battles, so like AoD there will not be trash encounters. Despite the title, I doubt we will fight a single rat.
I will buy this day one to support Iron Tower Studios, who are using the income from sales of AoD and DR to develop their next full scale CRPG ("Colony Ship" project).
