I remember being pretty defensive about this game at release, but I do still like it. I was given it for free as some kind of consolation gift for being one of the five people that bought the moba-y Q force (still the only Ratchet game I haven't completed to this day) This version was super busted when I played it. One mission just kept crashing at the exact same point where I had to screw in one of those big bolts, but for some reason it eventually worked.
I remember my biggest disappointment beyond the stupid name change for Europe was that it seemed to relegate the series best character to an afterthought (although as you pointed out, everyone's an afterthought beyond the villains and news anchors) I don't know why, but at the time it felt like they were trying to just make these games all about Ratchet. I kinda welcomed the focus towards shooting at the time, and I'm still a little amused that they were like "fuck it, everything goes to level 99 now" The core PS3 games managed to balance the shooting and platforming a lot better... But this game has a spider tank!
