The Second game was for the Playstation, which i'm sure you'll be able to find some where.

As far as I know the game's are all set in the same galaxy and are connected slightly. But there's usually a few hundred years between the story of one game to the next.
Actually, I think that the second one wasn't set that far from the first one as Claude's father, Ronixis J Kenni, was one of the characters in the first one. Claude tells his fathers story when you start a new game as him in the second one. At least I'm pretty sure that's what it was, unless they just gave the same name (last name and middle initial included) to one of the characters of the last one to Claude's father for kicks. But they also look similar.
