If you weren't "lucky" enough to have a glitched copy of Bubble Bobble Revolution and the free Rainbow Islands that came with the replacement, you can get Rainbow Islands now for a very reasonable price. Gamestop is offering Codemasters' sequel for $9.99 new, no broken Bobbles included. It's backordered on the website (which has happened since we started writing the story) but it may be available in a local store or following a restock online.
$10 is just about the right price for a game with a Metascore of 54. The original Rainbow Islands is worth like 500 million imaginary Metascore points, and if playing this one even evokes the arcade game a little, it's worth it. Also, $10 is like 1/6 of a copy of Gundam: Crossfire. When you think of it that way, it's quite the bargain!
