The cost of deleoping science is give at
The cost of development decreases with each civ that gets it. In patch 1.21, which the demo game uses with all 12 civs discovered the cost of the second civ getting it is 11/12 the cost of the first, the third is 10/12x ect.
Civs are willing to pay 1/2 the development cost to buy it, so if all 11 civs bought it at full price,you would get
1/2x(11/12+10/12+9/12+...3/12+2/12+1/12)=
66/24=11/4 of your cost, a tidy profit!
If only 4 bought it, you'd get
1/2x(11/12+10/12+9/12+8/12)=38/24=19/12, so you'd get more than you paid for it, and there would be 7 civs that got nothing ,which makes them less competitive in the long run, which means there would be less civs you'll have to attack to prevent them from getting the Spaceship
Even if only 1 civ bought from you, he'd give you roughly half the price of development, so you and he would be paying roughly half price, while the other 10 civs would be falling behind.
The other advantage none of your competition would be profiting by selling the tech first.
This technique can be the fastest way of multipling wealth (much faster than rush building), and if we pour all our resourses into it we can be first often!
