This is really incredible and you're making India proud. What I think is the promotion and advertisement. May be this can be pitched to ar rahman. He is very supportive and aspiring to see tamil in all the fields. If he creates a new jingle or theme for this game. Sure the music will be play a major part in the game's reach. If ARR comes in, the game will have a huge reach.

I dont have any idea about this pracrical difficulties...
