I'm totally an Xbox Live Arcade addict.  The allure of a quick gameplay fix, low price, and those low-hanging Achievements are too much to resist.  So I was curious to check out EA's entry into the Live Arcade field, a fireworks / rhythm game called Boom Boom Rocket.  While it's no Guitar Hero, it's no Fantavision either, and ultimately proves to be a fun little zen-like diversion. 

Very relaxing, actually... classical music and nifty fireworks, simple but fun gameplay, and very attractive.  I'm hoping more songs unlock through play though.  Otherwise that "download" link in the game is looking pretty ominous...
