Ok, pretty much everyone likes Mario, and there's nothing wrong with that. He's a well-rounded character who you just cant go wrong with. Choosing him as an avatar, however, shows a complete lack of originality and perhaps taste even.
Mario's been in SO many franchises and games it's getting a bit tiresome. You, Kenny, are the lapdog of Nintendo's marketing mascot who buys and follows whatever they push on to you. Choosing Mario out of the obviously more unique characters shows you have no mind of your own. Mario may have been cool back in the eighties, but he's been in WAY too many games to stay fresh. He's become a marketing tool, and not much more.
It's like buying water when there's apple juice, milk, lemonade, orange soda, and milkshake all in the same place. There's nothing wrong with water, per se. It's just that you can get it pretty much anywhere.
You sir, can kiss my... shoe.
