Personally, if Waluigi ever got his own game, I would totally play it. That or the Koopalings. On a related note, Gamervision has a list of the Ten Reasons Waluigi is Awesome; fair warning, the last one is a bit off-color, but it’s still a pretty hilarious list on the whole.
Also, the call for guest strips is still open! If you’re interested, please send your guest strip to Jackson at thesketchy by 6/28; keep ’em 900px wide or less, and suitable for ages 10 and up.
