Out of curiosity, since I’m always interested in the topic of specialists vs generalists in games:
1. Is there any benefit to being part of only one group (cult/society/faction)?
2. Is there any penalty?
3. Is there any benefit to being part of multiple groups?
4. Is there any penalty?
This includes things like favor payouts or influence gain or anything else that might be affected. I tend to prefer to focus my efforts in one area in games, but often that means being disadvantaged.
