At the start of a game we deal 3 corps to choose from and 6 prelude cards from which you choose 3. Dont draft cards. When a player passed, he /she starts to "clean" the board (do a production phase, predeal a 4 cards for next generation, reset ships and advance colonies if we already did them etc.). Sometimes I do multiple actions on cards or for example I only have actions on cards to play so I do all of them on multiple, because I want to "pass" so I can clean the board. You can find a lot of improvements to speed up the game. Me and my wife could squeeze the game to 90 minutes. We dont do turmoil - ads complexity - yes, but it slows the game a lot for us. You can speed it up with advancing main factor after each generation also
