Another figure warranted? Yes if it is an improvement over what's out there now. Compatability. Don't care. License. don't care. Morph Injection? Definately. Unless you can come up with a better system. The worst thing is having a figure full of morphs you'll rarely--if ever--use and having to scroll through all those dials looking for the ones you do use. Age? 18-35. definitely realistic and easy to use ;) Thanks for asking.
