I usually play on monarch and there are some techs I practically never research. Most are just dead ends and are not required to be researched at all. Also AI seems to prioritise these so usually it's not viable to get them as trade baits either. Here are my choices for useless techs: Archery - Not really needed at monarch IMO Polytheism/Monotheism - Not needed at all. Meditation/priesthood gives access to important tech monarchy + oracle if I choose to prioritize it. Horseback riding - Not a fan of horse rushing Feudalism - AI tends to get this asap and can be traded later if necessary Theology - I don't like to play religious game at all Drama - Not a culture player either Music - Free GA can nice for golden age but not really necessary Divine Right - See theology Military Tradition - Just unnecessary IMO Military Science - See above Obviously player with a different play style can find these more appealing or even necessary to get asap. Just tell me what you think of my choices and feel free to add your own.
