it looks promesing as a pack to sink your teth into after figgureing out the basic idea in the vanila game in a deep way ,but may desperatly need to have its ingame resources guidiance fixed concerning at least Angels raw material reffining structures UI
example if you say have sellected a product to refine in the Oil & Gas effinery plant it told uss in clear text what resource it wanted to peform the task ,but even if we engage the process and hover the crusor over the section were the icons for the refined products shows it still only tells uss what the raw material demands is to maintain the refining process.

leaving it upp to guesswork to try and figgure out wich building process refines what and if it is the thing needed to make the other thing to make the third thing to finely...make circut boards ^^ love the expanded raw mateiral handleing but if you need a seperate search engine app to figgure out its products when the ingame UI is so friendly for jsut hovering a crusor over icons ,then i fear its jsut a bit to fiddly to be pleasent and thats even provided you arent playing with any servere alien threaths.
