Excerpt: Assassin's Creed is a series I couldn't imagine playing on consoles with less graphical horsepower than the Xbox 360 and PS3. The two games released so far (ignoring the handheld games) have relied on the processing power of current systems to create massive, sprawling cities, incredible animations...
Conclusion: Assassin's Creed: Bloodlines has all the makings for a great continuation of Altair's story, but it's fraught with presentation and gameplay problems that keep it from becoming a truly fantastic experience.
Excerpt: Even as the series moves forward to the tale of Ezio in Assassin's Creed II, Ubisoft isn't quite ready to part ways with assassin extraordinaire Altair just yet. Assassin's Creed: Bloodlines puts him on the front lines of the secret war with the Templars.
Conclusion: You could argue that it doesn't make sense to compare Assassin's Creed: Bloodlines to its PC and console relatives, which it can't hope to replicate, and I would normally agree - except they are exactly what it is trying to replicate, with mediocre results.
Summary: In Assassin's Creed: Bloodlines, Altair comes to the PSP with most of the gameplay from the original Assassin's Creed intact. The graphics and world may be scaled down, but the assassin's moves and abilities are not.
Pros: A visually impressive PSP game, Free-running on a portable system is a thrill, Learn the fate of Altair
Cons: Several control issues, Lots of loading, Repetitive mission objectives, Short and easy
