During a recent secondguessing of my wip "Ferals", I noticed a couple of important things:
As the PC's is supposed to be practically owned by different organizations and groups, I started out making those groups very diverse, like different corporations, law enforcement, gangs, and so on.
I thought that was a good idea.
It do not seem as that was a good idea now, or rather it is, but not as directly as I thought.

I ended up with organizations that had very little or no reason to cooperate with each other, and as the Player Characters are owned, there are also very little reason for characters from different Corporations and similar to cooperate.
If I compare it to oWoD, not even members of the Clans, the Tribes, or the Traditions had it that bad.

So, after some thinking, I have thus far come up with this:
See to that the choosable groups and organizations has reasons to cooperate, like against common enemies, or limit the characters to only ONE organization or group.

Are there any other possible solutions?

Being members of the same organization is easiest, since then they will have common goals (but remember that organizations aren't monolithic and sub-groups can have different or even conflicting goals).

If they are members of different groups, then common goals or common enemies are needed, with the limiting factor being achieving those goals or defeating those enemies may remove the motivation to cooperate.

There can be complementary goals and causes that aren't related except that their goals or threats happen to be co-located. That can be interesting because it can get people together yet give different PCs different goals and concerns.
