Ok guys thanks for all the replies, i think some of the idea's were a little time consuming and i want to get this prize out before the release of the game, maybe should have organized it a little earlier:rolleyes:
It was always going to be tough to chose the right one but i have done, its probably the most simplest one and accesable to everyone on the board and rule out any unfair advantage.
The competition will open on Monday and end on Saturday afternoon, The prize, which i will post pics of on Monday will be posted to the winner on the following monday or as soon as i get a postal adress.
Thanks for your help people. stay tuned.
