The Italian site RPG Player has published a Celtic Kings interview in english.

GP: I have read, as have many others, that Celtic Kings mixes strategy, role-playing and adventure. How exactly will this be achieved, and what kind of gameplay can we expect because of it?
Gaby: The presence of heroes and items brings the role-playing flavor into a skirmish game. The experience of your heroes is very important for winning a battle. Sometimes whole armies are sacrificed just to kill an enemy hero.

"GamersClick: Of course multiplayer is critical in the RTS genre. What does Celtic Kings bring to the table that the online player hasn't seen before?
Gaby: We would like to give the players an environment to play out all these great battles that they are dreaming about. The scale of the battles is very important in this sense. We're aiming at more depth and strategic options without linking them to the click speed of the player."
