Tokyo Jungle takes elements of roguelikes and RPGs and applies them to packs of animals living in an apocalyptic Tokyo that's been overrun by nature. The PlayStation 3 exclusive—later ported to PS Vita—demands strategy, smart planning, and a whole lot of luck to survive.

It also starts you out as a pomeranian or a small cat, but as you complete goals with smaller animals you'll eventually work your way up to rhinos, lions, and dinosaurs. There's a wonderful sense of progression, even if most games last less than an hour before one thing or another gets you. It's a dangerous world, after all, but you'll regret it if you don't get lost in Tokyo Jungle.
