Ok, I will enter, though time is an issue for me.
I will at least try to get something done.
My idea is to make a board game where you can have 2-4 players each with their own side. The board will be around 30 x 30 square spaces.
You will move in a traditional snakes and ladders manner.
the aim of the game is to make it to the opposite corner and back again first.
as you role the dice and move along, you earn spending points equal to your dice roll.
These points can be used to manipulate a space on the board.
so you can either roll the dice and move and earn points, or forfeit the roll and spend some or all of your points on manipulating the space you are currently on.
you can make a bonus or punishment square, there will be various traps and treasures you can buy for various amounts of points.
they will be things like...
go back/Forward X amount of spaces.
Lose/gain some points.
miss a turn.
Roll x number to move
swap places with a player etc...
I am not sure about the actual actions at this point, I will have to play with the demo to make fun punishments and treasures.
so basically the idea is that you start with a blank board and a simple objective, as time goes on the board becomes more and more of a minefield. you not only have to cross the board but make it back too, so if you go hard on the punishments you may just set yourself back too.
the players corners will overlap so even from the start there should be some degree of action.
... oh and why not have some kind of fight if two pieces occupy the same square!
The more I think about this the more things I want to put in... I think i will start with what I have here and then see how far I can take it.
I'm not a complete idiot -- Some parts are just missing.
