i don't usually like to advocate or advertise drug use, but if you like to get stoned and play videogames, get stoned and play this videogame.
I could just watch the opening movie over and over again and be entertained (spinning green leaves, mushrooms, and singing ducks LOL), but the gameplay is pretty damn fun too. Running over people with a trashball is very satisfying (take that Japanese schoolgirl!). My only complaint is that sometimes the camera is a little funky and i get discombobulated, but that's inherent problem in most 3d games. As much as i love two dimensions, a game like this really shows the immersive power of a 3d environment.
And the music!!! I would buy a soundtrack in a heartbeat. The intro song and the mellow one playing when you're on your home planet are my favorites right now. I don't really remember the level tracks (i'm only on Make a Star 6), but i enjoyed all of them so far.
I think this game has a deeper message as well, concerning the cluttered and overly-materialistic nature of twenty-first century life. Or it could just be a game about picking shit up; i've been known to read too much into things in the past. LOL.
Anyways, the gameplay is simple and fun, the visuals are stylized and trippy, your father's quotes are strange and funny and deep (or just poorly-translated), and the music is catchy and funky fresh. I got the last copy at the third place i went to, so if you see one on the shelf, grab it up and go play.
