what is a 'game for metro'? I mean, functionally how is it different? It can have a live tile I guess, and it can have an app pinned next to it, maybe. that's it. do you really think people outside of tablet land are going to care about the difference one way or another? I don't care.
the windows store is not the only place you can release games on PC. functionally those games are no different to desktop games.
if people really can't tell something pretending to be metro like Chrome isn't metro... why is it going to matter to them that a *game* is running on the desktop vs in metro?
this isn't something like a twitter app, or an e-mail app, where you're going to want to embrace things like the share, search and devices charms, where the difference will be much more obvious. it's a game that runs full screen, that you don't print from, that you don't search within and that you don't email shit out of.
I don't love Pinball FX2 because it's a 'metro game'. I don't give a shit about any of that.
