I only discovered Light a few days ago and I think I'm in love. I adore the board game-like elements of the Control campaign and Patrol Zone supplement combined with traditional roleplaying. Any further supplements you produce for this game are going to be an auto-purchase for me - doubly so if they offer more campaign modes or factions.
One question though - the reward tag for the House of Dusk (pg. 44) seems a bit much. Am I reading it wrong? It seems like this tag obsoletes just about every damage boosting tag that doesn't also give you more targets hit.
