I played Impire last week, although my hands-on time just about saw me through the tutorial so I didn't get to summon any truly horrible minions. My dungeon was packed with scurrying imps of various sorts though and, later, with heroes too. The brief hands-on session revealed Impire to be a solid take on dungeon management, with a neat incorporation of simple overworld missions and combat that is more engaging than it first appears. It's also an attractive game and while you'll have to wait a couple of days for my full impressions, you can watch a few minutes of playthrough footage from the first scenario right now, which gives a good look at the all-important interface.
Paradox also send word that Impire now available for pre-order. It's £14.99 and is out on Valentine's Day. Awwwwww.
