Q: What are the most important research topics in this field?

Preface to the answer: Defining the field

so the group asks, "what is the field" 
possible answers: abm, spatial modeling
the word "geospatial" wasn't in the workshop title

what came before ABM? 
group answers: 
microsimulation
cellular automata

discussion on the roots of ABM

-statement: "complex spatial systems" is the field 
-"agent based modeling" is the tool
dissent: but "complex spatial systems" is also an approach


A: relationships and differentiation with respect to other modeling fields? 
the spatial<--interactions in space are non-trivial.
topology of relationships in geospace.

A: examination of empirical and theoretical connections-->feedback between the empirical and model frameworks.

What can the contribution of GIScience to ABMCSS?
Video game engines?

Topology of time
