Tom Clancy's Ghost Recon Advanced Warfighter 2 review at IGN.

"When it was released earlier this year, Tom Clancy's GRAW 2 was an evolution of the franchise. Improved controls, smoother gameplay and a deep multiplayer experience added up to make an incredible first person shooter. The port of the title over to the PS3 was impressive as well, which merely added to the legacy of the franchise. With the release on the PSP, you'd expect Captain Mitchell's portable sorties to be just as impressive as his console adventures. Unfortunately, that's not the case. Tom Clancy's Ghost Recon Advanced Warfighter 2 on the PSP is barely GRAW in any sense of the word, which should be extremely disappointing for fans of the series."
