Since I'll probably be the only one to mention it, I think i'll give an honorable mention to the NGage QD now. It got tons of flack, but if everyone gave it an honest chance it would be remembered for what it was; a really cool little device.
After buying Sly Copper: Thieves in Time last year for the Vita, I finally booted it up today. I've never played a Sly Cooper game before but fell in love with this one after the first level. The gameplay is tight and the music is awesome. Are the other Sly games as good?
