I loved the ambient challenges in Red Dead Redemption. Hunting animals, picking flowers, capturing criminals, fun times in the old west. There was one challenge that drove me nuts though--Kill five skunks. Before that specific hunting challenge, I saw skunks everywhere. When it came time for me to actually hunt them, I couldn't find a single one. It got to the point that if I saw a skunk scurrying through the brush, I'd drop everything--damsels in distress, a high priced bounty pursuit, anything--and gun that little critter down. I once spent an entire clip on one of those rodents. Poor guy didn't even see it coming.
I sketched this picture after beating the game, when I realized how absurd my whole skunk prejudice was.
