Something wrong with the uplaoding recently, the admin needs to fix that. now to strategy... The internet is a good late boost for science, something like 25% civwise, thats the best boost any single wonder can give you. sorry I coudn't built it, if I did I would trip domination as the research labs would quickly expand the borders. The JS bach is giving you an equivalent of additional luxury which is good if you have below 4. If you have more then 5 it's much less important but maybe you needed it to crank science one notch. The problem is music theory is off the main path, better trade it if you really want bach. Tank stacks can crash anything below infantry without arty support so it's no coincidence the arabs were crushed to oblivion, and you could use their own roads and rails against them. (shifting reinforcements in one turn and using the same tank to attack a city each turn). Thats the way to win spacehip in regent so it's time for monarch or emperor. Manufactring plant isn't so necessary for components unless you didn't have metros and even without them there are ways to prebuild the components. A metro will have 20 worked tiles of which half produce shields and most of them produce 2 shields with rails. Couple of mines produce 8 shields alone so you will have on average 20 base shields, then add factory and power plant/hoover and you get 40 shield which construct the most expensive components in 15 turns without prebuild. You could turn the surplus citizens to engineers and get 12 more shields on average so it's 52 and 12 turns per super-components, I might use one plant per empire if I can get a 120 shield city to produce one armor per turn or to produce the components in a tight race. Regarding ToE slingshot espionage is a waste on this level-you have tanks and they don't so no techs to steal and no reason to steal plans. It's high priority for AI research so you can trade it for something like the corporation. Espionage is also twice as cheap as electronics or mass production. Usually you can research it in 4-6 turns. It's also preferred to get replacable parts before ToE is built Better to use the slingshot in the following ways: 1) Atomic theory+electronics and then build hoovers- for peaceful victories. 2) On the motorized transport/flight line, something like steel+combustion- for warmongering. And be careful about flight if you base your research on super science city with the colossus, colossus would be destroyed, if you do use super science city with colossus research flight last unless you need it for war ASAP.
