I have EQ: Attack on Qyenos. I lost all my info with a ROM update and don't fell like going through all that Hell to get my character back up to the level it was. It's redundant and laborious. You also do a LOT of running around with no real direction and a LOT of standing around waiting for your health and mana to recharge... you might want to look into something else if your Axim's battery life means anything to you.
Sure, it's a cool game, but it's not for everyone. Give the demo a try and see how you feel about it. :)
