First thing to plan is the spaceship.
Stasis Chamber
Delhi will build Ironworks, Sushi headquarters, one Thruster and Stasis Chamber.
1) Prepare Thruster
2) Finish lab with 250 overflow (whip)
3) Finish Notre Dame with 470 overflow (whip)
4) Finish Thruster with 600+ overflow (800 base hammer cost)
5) Build Stasis in 2 turns with 2 chops.
This leaves plenty of forests for other purposes.
Docking Bay
New York will build Docking Bay. Need about 130 hpt and 4 forests.
1) Lab with 300 overflow
2) Hermitage with 450 overflow
Satellites+0: put overflow and 4 chops into DB.
S+1: build overwhipped Industrial Park (IP)
S+2: DB
S+3: overwhipped Hospital
S+4: DB
Casing 3 (to be settled) will need 84 hpt, 3 forests, 375 overflow from lab and overwhipped IP.
Engines
Thessalonique and Pasargades will build these in 6 turns.
Thessalonique needs 150 hpt, 3 forests and 375 overflow.
Pasargades - 100 hpt, 6 forests and 375 overflow.
This is a bit more complicated.
Fusion+0: Bureaucracy, Pasargades uses it.
Fusion+1: Nationalism, to avoid overflow reduction in Thessalonique.
Fusion+2: Bureaucracy, Thessalonique uses it from now on.
Pasargades
1) Whip palace and lab
2) Finish palace (must not be in Bureau).
3) Finish lab with 375 overflow (still must not be in Bureau).
4) Put overflow and 6 forests into Engine with Bureau boost and build Engine.
Thessalonique
1) Build lab with 375 overflow
2) Put overflow into Engine (no chopping yet)
3) Finish palace with 240 overflow (must not be in Bureau)
4) Put overflow and chops into Engine with Bureau boost.
The rest of the Casings are built in the same manner as the third one. This way I mostly keep for the spaceship forests which I cannot use now anyway. I will probably reconsider using Tours for this reason and use a new city for Casing 5 on a 3-forest spot to the east of Tours.
