I've had the Metal: Hellsinger sountrack on loop for a good part of the evening. The song Stygia featuring Alyssa White-Gluz from Arch Enemy on vocals has been particularly captivating. Probably because her clean vocals are mesmerizing.
I played the demo, and I'm looking forward to buying the full version once I get my GPU situation on my PC sorted out. A monitor upgrade is in order, too. 1080p is fine for me, I just need something in the 144 or 165hz refresh range. Shooters are pretty lame at 72 fps.
