Possible Idea for a SEIV spinoff game (or just a feature for SEV if there ever is one

[Nebraskan]

What I would like to see is a more complex resource and research system. Say instead of 3 types of resources you have 20 basic resources (a,b,c,...,t) and each resource can be combined with up to 2 others to make a 3 resource group (abc,abd,..feh..rst) and each group has to be researched to find out what it can be used for (weapons, propulsion,...shields, etc). What would make it best is that each solar system only has 5 resources max. It would force a player to explore and expand to find and exploit the other resources it needs to research the entire tech tree.
Just a thought.
