The PlayStation platform versions of Tom Clancy’s Rainbow Six: Vegas have had a bit of a tumultuous time. The PlayStation 3 and PSP games, originally scheduled for release at the end of 2006 to coincide with the PS3 launch, were delayed for months on end. Both games have finally shipped, but there were pretty big differences between the launches. While the PlayStation 3 release got plenty of time in the limelight with a healthy advertising campaign, helping to push a game that in most ways nicely lived up to the previously-released Xbox 360 and PC versions, the PSP title is almost entirely opposite. It snuck out to store shelves, its launch date so quiet that it surprised even us, and unlike the PS3 release, it unfortunately doesn’t live up to the series’ rather high watermark.
