Its not Land Land, its Round the Land. >< I do understand the confusion, though, because "Round" and "Land" used the same characters in this case. Its actually a bit of a pun. (say it fast: "RandoRando"). Anyway, its a pretty simple game. Its light fun, especially if you're a fan of the series. It basically goes as such: The Luffy pirates happen upon an island where they get split up and must go "Around the Land" to find eachother, collect treasure, and fight villains. Its a simple premise basically used to set up each area around one of the major story arcs in the series. There's the Buggy Arc, Kuro Arc, Baratie Arc, Arlong Arc, Drum Island Arc, Arabasta Arc, and Skypiea Arc. There's also one more area based around the new villain introduced in the game,
Its plays out like a fairly simple pseudo-2-d platformer. The formula seems to be 2 levels -> midboss -> 1 more level -> Boss. The levels I've played aren't particularly challenging, but they can be hard in some respects (enemies can take off a fair chunk of health). Maybe it gets harder later on. Before a level starts you can pick which character you want to play and two supports depending on who you have gotten so far. These characters will be your "extra lives" and you can also switch between them at certain points in the level. The rest of the game is basically straightforward, with the player going through the levels, popping balloons for money, killing enemies, and attempting to make it to the end of the level with one of the various treasure boxes you can pick up along the way. At the end of the level, money is tallied up and the characters either get a lifeup or powerup depending on said performance.
So, like most anime-licensed games, its not awesome. Hell, its done in Renderware. :| But the theme can carry it through for those who like it enough. Still, its some light fun.
