Well, I think u should stop this project. "Next-Gen" - by changing a little bit graphic, import to the game, make it different and called "NEXT-GEN", make no sense. Why don't you "enjoy" all the stuff here and make your game beautiful, better than "working" on this project. Do you think there are a ton of thing you have to do ? Time to create graphic, time to convert to FIFA file, time to test it... Are you sure it's compatible with user's current game ? Don't you think sometimes it causes loose data ? How do you manage the setup ?
Sorry, this project's not as easy as you thought
