I realized that seeing as we now have pretty decent terrain bricks, and other ballgames available, golf might be a nice addition. To me it seems like a fairly complicated thing to create, but then again it's not like I have any experience or skill in add-on making.
Whatever the ball would be, I reckon it'd probably have to be a bot for better collision and to avoid the fact that projectiles disappear eventually.
Just throwing this out there. Think it'd be fun. (old rich people RP??)
