I like Deus Ex, and Windows 8
Deus Ex is pretty awesome. And I've started a second playthrough just to get the Pacifist achievement and take up the side quests I missed the first time around. People complained about the boss fights, but I didn't really mind. They were rather easy (even on the hardest difficulty setting), especially the final boss. Up next, Warhammer 40,000: Space Marine!
I downloaded and installed the Windows 8 Developer Preview in a VirtualBox VM and I have to say it looks pretty good. Being able to access a proper desktop is nice, but I wish there was a way to get rid of Metro and revert to the classic Start Menu. Alas, whenever you click on the Start button, it takes you to the Metro interface.
I've had a few issues with the VM installation: the display drivers don't work and Internet Explorer 10 hangs when I open up the About screen, or whenever I try to open a URL, and Tweet@rama sometimes hangs the entire system on start up. We'll see how it goes as I'm still trying to break more things, but so far so good, I'm impressed.
