This is a tough one to pick. Really. There are quite a few memorable characters out there both iconic and obscure. However one character stands head a shoulders above the rest. A man who loves his miniature giant space hamster perhaps a bit too much. Yes, my favorite video game character of all time is none other than Minsc. Loud and a little unhinged Minsc is one of those characters that has stuck with me for the long haul. A simple character that served as a bit of comic relief and one who stayed with my son of Bhaal from the beginning to the end across hours and hours of gameplay.
