Hello, here are some hints on the game
The '2002 was a good year' skill is easy to get, just get a gun look up in the sky and look for a familiar blimp from 2002, thats right, its the same thing as Ratchet and clank 1, or 2 i cant remember.
If you wanna get rich fast.... i cant help you, the best thing to do its to rush through the game, and get challange mode, it is very easy to get money that way, i got millions very easyily
Thanks for reading, I will post more heheh
