Microsoft be a cold pimp, turning out its Xbox Live Arcade darling onto the uncharted streets of Windows Vista. There's no crawling into bed with a trusted XP customer for this version of Geometry Wars: Retro Evolved. Vista-only.
For its sake, Geometry Wars won't be working the MSN corner alone, as it's joined by fellow newcomers Bliss Island and Crystal Quest. The cost might have gone up (from $5 on XBLA to $7.95), but the experience will be over just as fast for the average john (patience, it takes practice) -- do remember to bring your Xbox 360 controller for an authentic experience. Play safe, folks.
