I'm trying to add a balanced AI option.  In gameplay.constants you can manipulate what the AI concentrates on...

    "playerAISharedDef
        table-Aggressive
            BuildShip 10
            BuildModuleTactical 2
            BuildModuleCivilian 1
            BuildModuleResearch 1
            UpgradeResearch 2
            UpgradePlanetArtifactLevel 1
            UpgradePlanetPopulation 1
            UpgradePlanetInfastructure 1
            MaxBountyBidCount 5"

However if I add a balanced option how would I get it to appear in game?  Is it possible to add a new AI type?
