That restriction to build stoneworks is one of the most
design choices I've ever seen. What's the purpose or flavour behind that?
Regarding techs, we need Calendar for Cotton, right? So it's probably our best choice. After that, sailing might be interesting, to get another TR for the third city. The free food is pretty nice, after all. Not sure how the timings will work, but we can even do it with a Cargo Ship, like I've suggested. It'd be worth +6 food right now, +8 after classical era.
Yuris is up.
Did you feel that 10 turns is too short for a turnset, T-Hawk? We can keep 15 turns, since Civ 5 (especially with our variant) has less things to do each turn than Civ 4.
