First of all, that's pretty bad ass your game made it on a system like that. Secondly, yeah it can hurt, but don't sweat your name not being there. I work on AAA games and it's always a new PA putting who put all the credits together. They're usually in crunch mode when making the list of names. It's not like they're maliciously trying to drive a knife into your back by leaving you out - it's probably the fact that they don't realize who even did what or where the game actually spawned from. Do you know many people who watch movies and make a shrine for the lead assistant to Mr. Depp? Only teh [sic] psychos. It's usually your friends and family who you're going to show the game to (the people that matter) and you'll be there to tell them how you made it. Props to you.
