One of the more invisible changes I'm making that has a big effect on the early game concerns bonus resources. I will try to get this documentation inside the game soon, but for now it only exists here!

1. ALL BONUS RESOURCES now provide 1 happiness (as opposed to the 4 happiness provided by Luxury Resources). This means that improving a bonus resource will create 1 happiness for 1 of your cities. Multiple copies do not create multiple happiness, and unlike luxuries, they cannot be traded away.

2. ALL BONUS RESOURCES now provide 1 science per turn in the Capital city so long as your civilization has access to a single copy of the resource. Multiple copies do not create multiple science.

3. EACH BONUS RESOURCE now has specific, modest bonuses which are unlocked over the course of various technologies. Having access to at least 1 copy of the bonus resource anywhere in your Empire will give you access to the benefits throughout your Empire. Most are fairly trivial amounts of food, with the exception (so far) of Copper at Electricity, and Fish at Sanitation, which provide substantial benefit.

This list is of course subject to revision, and the new resources from Resourceful will be added soon.
