lel I have Best of PSN Vol. 1 too.
It goes for $60 now, apparently. It's cool to have a collection of PSN games on-disc, though Tokyo Jungle's one of those games with a bunch of small DLC and none of it's included, nor was it ever bundled, which makes it kind of a crappy physical copy. So it's one of those games where you're better off just pirating the whole kit & caboodle.
Also for what it's worth, there's nothing that special about the Best of PSN disc. The games all just show up separately within the XMB, and you have to install them, so they functionally operate just like their PSN counterparts, but you need the disc to play them. Unless your PS3 is softmodded, of course. There are no extras or anything. Just four games as-is. No manual, either.
