Thing is, Geometry Wars captures that elusive essence known as fun&and reminds us that exhaustive prerendered cut-scenes, complex mechanics, and multimillion-dollar engines aren't the only roads to that very central goal. It's the Tetris factor -- the minimalist design and the addictive, score-chasing nature keep you mesmerized for what can stretch to hours at a time. It's when you reach hour no. three of a marathon session -- having entered a Zen-like state as you attempt to send your high score into seven-digit territory -- that you realize the simple truth at work here: In a world of interactive stories and photo-realism, Geometry Wars is just a really fun game. That's all we're looking for, isn't it?
