Re: Sparring games/ scripts???
Used to do some where each fighter is assigned a certain hand to punch with/ or a particular set of punches. (One might only have the jab while the other might have a cross and a hook) Lets you work things you normally wouldn't and find new openings with punches your not as comfortable with.
There was always ping pong as well.(You throw a 3 punch combo and they counter with the same one).
Also my coach used to tie two people together with a handwrap with about 3feet of leeway to make sure the fighters would work inside punches only. Pretty effective drill, gets you to rely on headmovement a lot more.
