Hi!
This is not a proper check list, but it is how i do my turns on AGEOD games:
First i read the log, all messages, clicking on the ones i find interesting so i'm taken to the location on the map. Red messages (like battles and events) open a new window with aditional info. The log will give you a detailed idea of all that has happened during last turn.
Sometimes during the message checking i give orders the the units the message talks about right away. Usually simple things like changing postures, sending recently recruited units to the front, etc. Just to get it out of the way
Then i check the ledger, to see what political options i have available, to check replacements (and buy what i need and can pay for) and take a look at the last page to see how the game is going (objectives, PV, NM, relative strenght etc)
Then i check the regional decisions and decide if i want to use some.
And finally, i start giving orders to my forces on map, using the shortcut keys to cycle through all of the unlocked forces:
E for land forces
T for naval forces
I give orders to each stack, move or rearange them as needed or let them rest for a turn (using SPACE key).
When no force is shown with E or T, it means everybody has orders or will rest for one turn. You will never forgot ordering forces this way!
While giving orders, don't forget to check the supply situation of your forces, their cohesion, possible command penalties...
And of course, you should check the enemy forces on map, and study the info given on the tooltip to know or make a guess on what you have opposing you.
And that's all... press next turn and start all over again
Regards!
