A great game, with just Daxter and not Jak.
My personal favorite minigame in this game, is bug combat. It is like rock paper scissors TO THE MAX! You collect bugs in your adventure, and give them more power or tokens, to gain an upper hand during combat. The 3 attacks are trap, countering claw, claw, countering spit, and spit countering trap. You can use the tokens you give the bug to change attacks, or defend against ones you are hopeless against. You can even heal your own bug!
All in all, this is DEFINITELY worth it and even comes in the silver PSP package (where I got mine)
