There is fair amount of chess players on server who would love that idea:
Making Virtual Gameboard playable for two instead of vs.AI
Why it is a good change?
> We gather on server to interact with each other.(those who wanna play alone will still have Orion etc.)
> Playing agianst AI engine in chess is painful.
> Making your own chessboard is also painful. It is easy to make board but very hard to find substitute for pieces.
Difficulty in code: Hard to tell, but it is a change in something already existing in the game.
Alternate. While writing this post i came up with another Idea:
Cardboard chess pieces!
+ even easier to add.
- shitters may steal your pieces during ongoing game.
