Northern Pike said:A lot of confusing things have been written about AI civs and the tech rate, so this is a real question, not a rhetorical one. Are you saying that the difference between India's being the last of eight civs to research a given Modern Age tech, and its being the last of four, would be insignificant?
3840 to 4388 beakers according to techcalc for robotics in your case. Not insignificant, but also not a lot. And both values are a lot for a civ w/o libraries and universities.
@ThERat :
The Lighthouse grants movement on sea not ocean. So you cannot move with a goto (or holding the mouse button) into ocean.
Still where the advanced galleys are, there are sea targets to reach within one turn (over ocean tiles).
The more southish galleys have to move first northish into the vicinity where the northish galleys are.
This works okay, but don't expect to be able to set a route for more than one turn. The routing algorithm doesn't take into account that it is sometimes better to stop short of using all movement and calculates then nonsense routes (I've seen it give 20 turns all around the world, when there is a save 2 turn route, which just needs the first leg to be one tile shorter).
So you have to plan the route yourself. The big leg over the ocean can only be made at certain locations e.g. where ther northish galleys are now.

It's btw just the same w/o the lighthouse if you have a crossing from coast to coast over sea/ocean.
