Over 9,000 is built around ever expanding dice pools (characters get more dice as they get more powerful) and the risk/reward of allocating your dice to actions like firing ki blasts, or keeping them in reserve to defend yourself with reactions like DODGE!. Unlike some RPGs where boss fights are hampered by the action economy, being able to do more things at once as you get stronger is a core part of the system.
There's a system to create your own custom techniques or recreate moves from your favourite shonen anime. If you spent your childhood doing anime power up screams and shooting imaginary laser beams at your friends maybe you'll enjoy this.
I've been building and playtesting this with my friends on and off for about 3 and and a half years now. I'd love to hear any feedback you guys have, hope you enjoy!
