Summary: Katamari Damacy is a good example of what's called a "Japanese niche game," a game that's designed very specifically with the unique Japanese sensibility in mind; but to create such a game that doesn't lose anything in translation to English takes an extraordinary amount of talent. It won't appeal to everyone, of course; gamers who hate this game usually cite its goofy plot, or its simplistic control scheme. But to me, those things only add to the charm of this game.
Summary: This game is the best! It's so simple, but really really REALLY addicting, and it's hard to beat. I'm 14 and I LOVE it to DEATH! It's a great game for all ages, actually; smaller kids have fun with in, big kids can actually beat it. I just bought the game a few days ago, but i played it over the summer and I had soo much FUN! The concept is ridiculously funny. Trust me, your kids (and probably you, too!) will love this game.
Summary: I really enjoy this game - quite a departure from the run of the mill shooter or action game. Colorful, funny, intuitive, a bit crazy, and with captivating music. How come American companies don't make games this imaginative? When you finally start rolling up really big things, like cities, and your Katamari is so big that it bumps up against clouds, you will be smiling at the pure brilliance of this game. A perfect delight.
