In what equation could they work together (equations at the bottom), without making the other redundant while maintaining a social output?
Here are some clarifications: scarcity stands for the bottleneck of traffic, when there are so few objectives around it causes a crowd, in different systems this will have different effects. Abundance is the opposite. World of Warcraft uses a closed system, Guild Wars 2 uses an open system. World of Warcraft is highly social during high traffic bottlenecks but becomes anti social (almost combative) in low traffic. Guild Wars 2 is Asocial during high traffic bottlenecks (people around you have no negative or positive impact on your person) a large down grade from the alternative, but in low traffic it becomes moderately social, not ideal but acceptable and better than the alternative.
Scarcity + Closed Groups = Social
Scarcity + Open Groups = Asocial
Abundance + Closed Groups = Anti Social
Abundance + Open Groups = Social
