Andrw Fletcher plays some WarioWare: Twisted, and thinks that it's quite the casual gaming experience:
"All too often, I snobbishly feel just a little bit too mature and intellectual for this gaming lark—although clearly not so much that I avoid using the word "lark." I mean, was Resident Evil 4 more than just a glorified, exhaustive shooting gallery? Is San Andreas the industry's conception of a mature, sophisticated narrative? Frankly, the number of videogames that compel me to reflect upon them intellectually (as opposed to just critically) is worryingly small."
