Disclosure: I just started working for Microsoft, but I think this would be my opinion anyway.<p>The Windows 8 app market looks still pretty much wide-open. Nevertheless, we can expect with some confidence that a few months from now there will be approximately a gazillion Windows 8 users looking for apps.<p>IMHO, this would be a <i>really great</i> time to have a few nice $2 game on that app store.
