An Entertainment Software Rating Board listing for Best of PlayStation Network Vol. 1 has been discovered. What cuts it for "best of" these days? According to the rating, this first bundle contains Tokyo Jungle, Fat Princess, Sound Shapes, and When Vikings Attack.
Depending on the price, this could be worth picking up. I still play Tokyo Jungle on a near-weekly basis (gotta earn enough points for that last unlock!) and cannot recommend its wacky, stressful, and at times amazing brand of gameplay enough. Being chased down by a pack of enraged hippos while low on health and down to your last animal is a truly harrowing experience. Sound Shapes is pretty cool, too!
