Hm, a little off topic but... if anyone has ever played any of the "Legend of Zelda" game. Take a look and see witch hand his sword is always in. "Links awakening" and "Link to the past" seem to be a minor exception however. Link ambidextrous there... depending witch side you face... but over all... Link is a lefty. *cheers* Go Lefties!
Anyways, I'm left handed though there seems to bee a few things I can only do with my right like throwing and catching... kinda makes baseball a little difficult for me... can't reallt throw the ball... wile wearing the mit aswell.
Computer, though I type completely with my left (no homerow keys for me... feels weird) though the mouse is always in my right.
Writing and eating, always with my left... though can eat aleast with my right if I try.
Scissors and such however are not all the difficult for me however... guess I just grew up using right-scissors... and can use just left aswell.
Additionally, being a bit of a sword collector irl... I tend to wield them with my right...
Anyways... selecting witch hand to use in game? Mmm, interesting... though I doubt it would really hold any advantages or disadvantages... your just simply more skilled and (possibly) stronger with your other hand. Though might be a bit odd fighting a righty with shield... when your a lefty with shield...
"Its like I'm looking into a mirror... that's trying to kill me."
either way... not visually possible but... could always RP it as such.
