At the moment you can start with 32 coal and convert them to iron ore.
Convert the 32 iron ore to 16 any item tier 2 -> 8 any item tier 3 -> 4 any item tier 4 -> 2 any item tier 5 -> 1 refined hazard concrete or lubricant barrel.
The refined hazard concrete and lubricant barrel are both a 1 to 3 ratio, so you can make 3, 9, 27, 81 ... infinite.
When this infinite resource generation is running, you can convert the refined hazard concrete to rocket fuel for the rocket on a 1 to 3 ratio.
For the tier 7 items there are no infinite 1 to 3 conversion chains, but with some 1 to 2 or 2 to 3 you also get infinite items.
So once you have those chains setup you can make the other items needed for the rocket or space science pack.
At that moment the lower tiers are not needed anymore.
A solution would be to include the science packs to the recipe of the next science pack.
That way, to make the 729 coins worth space science packs, you would need all the precious tiers.
1, The ratio is random. The code is like random(1,3) into random(1,3). It means you get 1-1,1-2,1-3,2-1,...,3-3, all the 9 ratios randomly.
2, I tried to hard code all the ratios, but still met a lot troubles that made my game awful.
3, Now you see the recipes are generated with random ratios, any suggestions based on this?
