Yeah, I too hope it has done well for Sony, as they're pretty much the only publisher outside of Nintendo who are still supporting 3D platformers; a genre I hold dearly and have missed this generation.
Amazing game - my favourite Vita game and I'm only midway through episode three.
If this was a Nintendo game it would have about a 92% Metacritic score. I hope it has sold well as it's the first 3D platformer I've enjoyed other than the Galaxies with invention at every turn.
I really hope for a sequel and the rest of Sony's PS2 stable I never tried or got in to hitting the Vita now.
I need to get back to this, when I've finished Batman: Arkham City. Having two open world games on the go seemed a bit much, so I've decided to concentrate on this for the moment.
Also, Sanzaru are clearly a talented developer and I hope they get a shot at developing their own IP at some point. Although I'd gladly see a couple more Sly games from them, I'm a firm believer in letting a studio try something new every two or three games to keep their enthusiasm and creativity flowing.
