Pbem ruleset errors

[SunrisePink]

If you chose a MP2 ruleset for pbem games two AI players (so you have 6 at maximum) are created and the game will be broken.

I experimented with this before. In order for PBEM to work, there are some special server settings that need to be set. Normally when you start a PBEM game this is done automatically, but when you change rulesets, I think some of these get reset.

Here are the special PBEM settings:

Ideally, these would be re-applied when you switch rulesets, but you should be able to set these options manually in the console, before starting the game:

I think these are the critical settings:

/set phasemode PLAYER
/set aifill 1
/set civilwarsize 1000
/set barbarians disabled

phasemode makes players alternate moves (instead of moving simultaneously). The other settings are basically all preventing the game from creating any AI players.

These next ones may or may not be necessary. You'd have to experiment:

/set nettimeout 120
/set netwait 15
/set pingtime 30
/set pingtimeout 120
/set maxconnectionsperhost 256
/set scorelog enabled
/set ec_info=enabled
/set ec_max_size=20000
/set ec_turns=32768
/set contactturns=0

I think contactturns=0 essentially disables diplomacy, which doesn't really work in PBEM.

These last ones are just preferences. PBEM normally starts you with extra money and units, and makes techs easier to research.

/set startunits=ccccccwwwwwx
/set landm 50
/set gold 500
/set sciencebox 50
