Once you get so far into the single-player puzzle game, you are given the option to continue the game by buying new puzzles. WTF? Lame. This also applies to the "Vs. CPU" mode, in which you have to buy a separate pack.
Lumines Live: 15 dollars
Puzzle/Mission Pack: 5 dollars
Vs. CPU Pack: 3 dollars and 75 cents
It's not that much money, but they should just include it all in one game, really. It's still really lame.
I wonder what the PS2 version of Lumines will have to offer...
