I'm a part of a Pathfinder group. We meet every Friday night at 6-7, and play until 11:30. We have been meeting for the past 2 months, and the people in my group are pretty great. But our party is a real piece of work. The main problem with our group is that we have no true group focus. We aren't together in one cause.
It all comes down to when we began our group - everyone vied for a "silent stoic type," with a mysterious backstory and [can't remember name | is practically mute | is married to DM | is new player, so RP is secondary | didn't bother with a backstory in the first place]. Multiple times have people in the party said "If you stepped in the way of my fireball, I'd pretend I didn't see you" or "I don't care for anyone in the group."
The last week's game was atrocious (we just made the change to homebrew adventures). Basically, we got shoehorned into doing a quest for a character's backstory - but that character won't reveal to the rest of use what it is that we are doing. So essentially we're doing very tiny pieces of a larger quest, without any real knowledge of the quest, because the character doesn't trust us.
I believe the problem arises farther back. When we created our characters, nobody took the time to have our characters have integrated backgrounds. All of the characters are true neutral or CN, so they have no reason to care (or that's at least the roleplay that is presented). We can't simply remake all of our characters because we're lvl 6, and people generally like their characters.
Question restated:
How do I get a group of adventurers that don't necessarily care for each at all to find passion in each other, and become a great RP driven group?
