Simultaneous mode is method of turn resolution usually used in multiplayer games. It is intended to eliminate any advantages/disadvantages created by turn order in sequential games.
Simultaneous mode places the game into a configuration where all orders are resolved simultaneously. When you take your turn, you are simply giving orders, you will not see your units move at the time you give orders as with Sequential mode. After Ending your turn, all turns from all players are computed and the results sent to each player.
Some of the ramifications of Simultaneous Vs. Sequential.
- There is no tactical combat in sequential mode.
- When giving movement orders, realise that all ships move simultaneously. If you are trying to intercept a ship/fleet, giving a movement order to that units current hex will not necessarily ensure interception. Because of this, combat usually occurs at destinations (planets) and choke points (warp points). A possible tactic, if timed right, is to plot a course to a hex in the suspected flight path of the ship/fleet. If the unit is under orders it will take the shortest route to it's destination. If you can anticipate the destination, you can attempt to place an intercepting ship/fleet in the path and the other unit will move into your hex thereby initiating combat. The obvious counter is to program ship/fleets flight paths to use non-optimal routes by giving multiple move commands to various hexes enroute.
- When converging multiple ships/fleets on a single hex, they will each fight a combat as they arrive. I.E., if two fleets equidistant from a planet both are given orders to the same planet and one ship/fleet is faster that the other, the fast one will arrive first and combat any enemies there. When the second fleet arrives, it will then fight any remaining enemies. Further, when the fast fleet enters the hex initially it will use it's offensive/attack strategy. If the fast fleet survives and any enemies survive, then when the slow fleet arrives, the fast fleet will adopt it's defensive strategy in combat with the remaining enemies.
- Launching units (sattelites, fighters) only gives the launch order, units will not be launched until your turn is ended.
- Transferring cargo also does not occur until the turn is ended.
