PAIN is good actually. To be honest, between that and Everyday Shooter I'm not sure which one I would have picked. It could very well be PAIN for me.
Anyways, the top three releases so far for me (excluding Warhawk/GT5P) is PixelJunk Monsters, SSHD & Fl0w.
Also, Super Rub'A'Dub is the most underrated title.
