We just started working on a new backyard disc game for a local toy company and group of invetsors. (We spent 5 hours prototyping some of the parts tonight and while its not complete its coming along quickly).
While I cannot discuss a lot of the specific details yet, its a lot more fun to play than I initially thought. Accurate disc throwing skills, good hand eye coordination and quick reflexes help, but anyone can play. Its easy to set up and only takes about 30 minutes to play a game and about 30-40 feet of room.
more details to come!.
