Add "game lobby parameters" to all missions (or some kind of module) so it is possible to change the date and weather of the mission just before game starts. So there is no need to create several mission versions with different date/weather setups.

Date/weather setups can change the gameplay in a mission (in a bad/good way but at least we can test it more easily):

• day/night

• fog/no fog (long/short distance enagements, snipers become useless)

• waves/no waves (boat gunners can shoot better when no waves)

• thunder/rain (no longer possible to hear footsteps/sound/wheels of enemy infantry/vehicles)

• etc
