Yep, a person with some decent punching form isn't going to hyperextend their elbows.
That's not the problem though. In the hunting game if you shake the gun like you would if you were reloading it. (Holding the fore-end and shaking it back and forth once) Nothing happens. To get it to reload you have shake it like crazy, up down and all around.
When playing the boxing game, my 6 year old niece is swatting the air like she's being attacked by bees and no one can beat her.
You can play the boxing game with decent punching form and get knocked out by a 6 year old girl, or you can play to win and hyperextend your elbows.
If a 6 year old can win all the time without form, she's not going to practice good form to lose.
