Does Boone have any more quests after he joins your party? Cassidy had a whole long line of quests to finish once she joined my team, but I've had Boone with me now for hours and hours and have traveled half the game with him... I haven't been able to find or start a new quest for him.

Isn't there supposed to be another quest involved with him after he joins you? If so, how do I get it or start it? I've gone through all the dialogue options with him and can't find one.

Arcade Gannon and ED-E also had a quest after they joined me... so not sure what I'm doing wrong with Boone

Boone does have a quest that starts after he joins you. Should he die, you'll see its name in the failed list.

Basically, to get Boone's quest, you have to go out of your way to kill Legionnaires wherever you find them. Once you've killed enough legion troops with him, he'll start to open up with you and talk about Bitter Springs. Do that enough and you'll get his quest.

Ahhh.. much obliged good sir.. that would explain it, I've been holding off on fighting Legion .. guess it's a time I went legion hunting hehe (been staying somewhat neutral between NCR and legion... but guess I'll side with NCR on my first playthrough so I can see boone's quest).

Well, after you get the platinum chip, Caesar will forgive you any crimes you committed for one time only. So if you wanted to, you could slaughter your way around Caesar's territories with Boone and get his quest, then get the chip, and then still choose to support Caesar. Boone will hate you forever if you do though, because for obvious reasons, Boone hates Caesar.
