One last thought on Towers of Battle. It's much more economical to make it a card game than a board game, but that still requires a LOT of cards. Perhaps if each card had two letters and you could form a word with either letter on a card? Bonus points if the word is formed from letters in the same row. Bonus points if both rows make a word? You could even include in the mercenaries on the cards with the sword and shield symbols. Hm!
