Yeah. The bosses aren't as good as the previous games in the series, but I've always preferred Human vs. Human style bosses in general. There's also some gameplay quirks I don't like, but hey, PSP port. It still has a good story, good characters, good level design, a ton of new gameplay options, and actual character development for Big Boss. This should have been MGS5.

Black Turtle did a pretty good job.
