well... I want to ask, what do you like to play most ?
and then... what do your friends (who's going to visit your game room) like to play most ?
I guess that will help you decide...
as for dart... I have a friend who got a dartboard...
and a backboard... but that doesn't matter....
when they drink... they will play stupid games...
then they'll try to throw darts at 10 ft, 20 ft, 30 ft away...
far enough that soon or later... they will get a hole in the wall....
so, if darts, I'll say use darts that can't get on the wall...
plastic, magnetic... whatever....
ps: my friends wall has holes all over surrounding the dartboard...
