In turn baced games there can be one serious problem with multiplayer (and to a lesser extent single player) Long turns.
I would like to beg, to plead, that elemental work on a simulare system to Risk 2 (i belive it was the computer game Risk 2) and MOO (amounst others) Seperated orders and excution phases!!
In one phace you give orders to your troops, arrange your diplomacy, set your contrucition / troop buying.
Then you hit end turn, and phace two happens, all units on all teams move, status of towns is updates, resourses are generated battles happen, and then the turn ends.
All teams can input thier commands at once, all commands get exicuted at once. AI's don't have a benifit of being able to order their troops faster, and claim things before human users just because they send thier move commands sooner (Happens in GC, really sucks for getting special resourses). and in 5 player mulitplayer games people don't sit uselessly waiting for
(average game turn) durations.
Also it greatly reduces the load on the host servers, updating in real time the possition changes of all players peices, all AI peices is asking for lag and computer to computer disagreement on which troop got where first.
Keep it simple, keep it fun, Don't have 45 minute delayes between turns.
Simutanious orders! simutanious action phases!
Please please please please please please PLEASE!
Live long and prosper
