I have always wondered how great it would be to have this old game Crossbows and Catapults on ios. I used to love this game and it would work great with multi-player. Is there anyone that remembers this? http://boardgamegeek.com/boardgame/2129/crossbows-and-catapults
I do not know that board game, but Siegecraft was was compared to it by several people during beta testing. http://appshopper.com/games/siegecraft
Not quite the same, but OLO Game scratches that itch a bit. Would be great if they took their engine and made something along the lines of the old game...
