well...
I would really like to see a Payback version in sprits, but it would have to be different...such as, no powers or kung-fu. Make sprite guns and cars to fit the Payback environment more. If you add most of the story of Payback to it, this will OWN!!! But as it is, it's just OK. I'll give it a "3" but I would like to see this made again but longer and without the kung-fu stuff.
P.S.: In case you might need it, the main idea of Payback is that a guy gets betrayed by his partner and gets his money stolen. He then has to go through high ranking thugs and bosses to even see his money. Then the dirty cops come in and he has to find a way to keep them away from his money. You know how to fill in the rest. Good luck! :)
