I had completed both previous PS3 Ratchets and had the following perks activated automatically when I started the new game:
-My Tools of Destruction save file classified me as a returning customer when I visited A Crack In Time's weapons-vending kiosks. I was given a discount. Thanks to the lower prices and my collection of new bolt money throughout the new game, I found myself lacking money to buy the next available item in the game only once.
-My Quest For Booty save unlocked the pirate hat you see my Ratchet avatar wearing atop this post. The avatar appear in the game's community section, which displays a variety of player accomplishments and stats, shows leaderboards for many of those accomplishments. Players can customize their Ratchet avatar or look up the records and avatars of their friends. The avatar is essentially a visual shorthand for some of the things you've accomplished. For example, the pistol that Ratchet is holding in that shot looks as it does in the game, where I attached mods and selected its paint job.
