Hi! I haven't played Dungeon Command yet (I've got a copy incoming) but I can tell you that you WILl be able to play two players with just one box. In the rules there's instructions on how to play two players with just one army box. I would have to imagine that it's not the optimal way, but it does at least allow you to try the game with a small initial investment.
Lolth because e read in some thread that its the best for a starter, and goblins because i Love goblins in MTG, i have 1 hell of a legacy deck of goblins. I like board games like WoA or Wow:tag wich i own both, in WoA i find myself and my friends strugling to solve the dungeon puzzel in Wow:tag i like the competitive game play and the card based abilitys.
As a Mtg player for so many years i like a skill based game i like to put a smile on my face when i win a game because a tought further than my oponent, i think i will love this.
Btw i have descent 2 edition comming on the way. =)
