Ratchet & Clank HD Collection?

[849]

I recently bought the HD Collection for Ratchet and Clank on PS3, and I noticed on the back of the game it says Broadband Connection required, is this here just because you can play online/use leaderboards/etc... ? Or do I actually need an internet connection to play the 3 ratchet and clank games? If I do I am not going to open the wrapping so I can return the game because I can't get an internet connection on my PS3 because of a problem I have with it
