@Seraiel: With alpha beeline approach, you aim to trade for a lot of early and cheap teches right? Don't you worry about wfyabta limit or what is your way around it? Picking opponents with high wfyabta, winning early or vassaling/getting friendly with a good techer early? Do you recommend trading even for cheap teches from AI or purposefully saving trades for bigger teches? Other thing that comes to mind is that deity AIs themselves get to alpha rather early and without a great start they can have it or at least have stated on it which lowers the trade value. Or is around 2000BC, which you mentioned, early enough to avoid this? Sorry this is a bit off-topic but I got curious about this.
