A mix of improvements from the first elevate the mechanics, but changes to the core gameplay harm the overall experience.
I know I'm going to be in the overwhelming minority here, but I have seriously mixed feelings about Ratchet & Clank: Going Commando. On one hand, the game drastically improved upon some of my gameplay complaints from the original title, on the other, it went ahead and created a whole new set of problems. Lenghty fetch quests and far too many required mini-games made the game feel drawn out and the overwhelming combat drastically overshadowed the platforming. This hurt an important core element of the game leaving it unbalanced, unfocused, and devoid of an element of character it once had before.
