Yeah, indeed it sounds like FF to me, but it IS a cool idea tho.
To Dannythompson: Indeed, summoning is done in alot of MMO\'s, but in most of em it\'s an already existing hostile animal that is summoned to fight for you. What these people are suggesting are completely new creatures that you will never find running around attacking you, and that gives it a slightly different meaning.
This is a cool idea, but I don\'t know if it is realistic...mweh..it\'s a bit of scripting, some new creatures to be created...Dunno..
