A 'Path Game' - My js13k ideas - 1 day to go

I've played a lot of the board game Carcassone over the last few months - a brilliant and famous game. I am especially enamoured of the 'road game' in Carcassone which involves building roads from the tiles and claiming a segment of road as your own.

Carcassone looks like this:

So the road pieces (white roads on green) are essentially a lot like the this game which has existed in various forms throughout my life. (this is the windows 95 version called 'pipedreams')

So these concepts are at the centre of what I want to do: a square grid on which you place tiles to form pathways(like Carcassone and pipes); a turn based two player game where your paths can block and interfere with your opponent's (like Carcassone); which has targets you needs to reach (like pipes); and which you can see the future tiles (like pipes) and plan for them.

Additionally I'd like the game to be fair in the sense that no luck element is involved and both players have equal opportunities (Carcassone is not like this) - thus a symmetric board and identical draw of new tiles for both players. 

Tomorrow we get to know the theme and can start thinking about how it might look (branches of a tree; neurons in a brain; roads or really anything that has paths and flows).

Plan to start the programming in earnest next week.
