Michael,

As an experienced developer you must have had an idea of how relentless users would be with their requests for new functionality. so...

how do you determine which requests are actually useful advancements vs cool wiz bang stuff?

When you had the idea for MOI3d did you have an "endpoint" in mind or were you prepared to just keep writing and rewriting until the zombie apocalypse?

How do you prevent "mission creep"?

Do you have a desire to expand beyond a one man operation?

Do you plan on developing any companion products i.e. renderer, analysis tools (FEA, flow dynamics, etc)?

Every developer I know has one or more significant personality maladjustments. Whats yours?

Thank you for all your hard work. It must feel pretty good to contribute as much as you have to design software.
