Here are my suggestions:
- New religions: Spiritism, Wicca, New Age, Jainism and Canaanism
- New economy civic: Vegan (disables all water and land animal resources and all mounted units; +3 food, +2 hammers and +2 commerce from non-animal food terrain improvement (farms, mills etc.); +4 health on all cities; +3 happiness on cities with Hinduism and Buddhism (and New Age and Jainism considering my suggestion above)
- Extra civ pack!
- Chooseable final era option: for example, I would choose to advance only until Medieval era, ending the tech tree on the last techs before Renaissance era-advancing ones.
