Revising my earlier comments ... if your going to port this to a game it really depends on the game. A multi-user RPG probably would not be best with SOAP because of the (possible) Lag-time involved in the passing of messages (you wouldn't want to still be trying kill the orc someone else killed 3 rounds ago) ... then again this is exactly what someone was talking about on the Axis.apache.org website so who am I to talk?
