Its major strength is that it's totally unique. I've never seen or heard of a game where the entire goal is to survive as long as possible without making any real progress. It's kind of like an open-world dungeon crawler with no ending. And that's a super cool mix. The huge variety of animals appeals to the animal lover in me and the destroyed city landscape appeals to the Doomsday fan in me. The map of Tokyo is the perfect size. It's just big enough that it feels like a trek to get from Point A to Point B but it's not "too big". The graphics are pretty budget, which is fine. The plot is actually surprisingly intriguing and the ending wasn't half bad either. Getting the plot on the other hand was a pain. Solid game all around.
