- Ratchet & Clank: Going Commando was the first game to introduce player loyalty rewards. Specifically, if you had a save of Ratchet & Clank on the Memory Card in Slot 1, you would get free Ratchet & Clank Weapons, presuming you bought them on that save. Up Your Arsenal would continue this trend by using the same method and rules to get free weapons from Going Commando, as well as give you a 10% discount on weapons if you had a save of the original game that had earned the Hologuise gadget. A Crack in Time would also give the player a discount on weapons from Tools of Destruction if they had that game's Game Data, or a skin if they had Quest for Booty's.
- Ratchet & Clank 2 was also the very first Ratchet game to have upgrading weapons, a mechanic that was so influential to the series it has been included in almost every title since. Ratchet & Clank had a similar concept through the Gold Weapons, however they had to be paid for, rather than upgraded with experience.
