welcome :)
Nice to hear that you've learned your lesson from this failings and now have a better plan for getting things done! Just do it step by step and don't be afraid to ask anyone else if you get stuck :)

The location-based smartphone rpg could still be something new, or is something like that already in the stores right now (a real, maybe round based, rpg?)? Since this principle is now known and accepted by a huge amount of people, maybe you still have a chance.. Or let it be just to reach your goals to be proud :)
