I'm looking to create a mobile game.  Obviously, this game will be anime inspired.  I'm thinking that you'll choose your character type by which how you'll fight.  Magical Girls (guys), Martial Artists, Samurai, Mecha Warrior, etc.  You'll fight various beasts/monsters that may drop Chakara Stones (these are stones that you'll need to collect, maybe meditate on.  For example, the Red jewels will associate with your Root Chakara -- physical needs such as food, water, the necessities of life), the Orange gems will be associated with your Sacral (creativity, etc).  so on and so forth.  Gems evaporate with a given time frame.  So Red gems evaporate faster than Orange gems do etc...)

As you gain Gems, you'll powers will increase / unlock new powers/moves, etc.

I want to create this game using a basic easy to use and open interface like Asheron's Call had.  Essentially, if you didn't know, you can level up any skill or attribute at any time, so long as you've got the available XP (eXperience Points).  I'm thinking that to move your character around you'll use the motion sensors.  Such as tilting up or down to move forward or backward, and tilt left or right to move in those directions.  What do you think?
