That would be 42 - 21 SY's building 21 stations for SW components.
However, echoing what others have said about the complexity of the game, I just have 2 comments:
1. To me, half the fun of a game like this is figuring out how everything works *without* delving in the manual except for the basics.
2. There is not a team of developers, just 1 developer (singular). As Atrocities mentioned, a strategy guide for this game is an incredible indertaking. For me, I'll take repeat playability over a slightly lower-quality manual / guide anyday.
SEIV is still by far the best game for my money I've ever purchased. Period.
