Does someone wish to remind me what the 'SJ's FTL map' does for the game.

Sorry, but I'm to tired to search for forum for the answer at the moment.

The map features a "Hyperspace" area in the center of the map. It is 4x4 systems in size, and each galaxy map square is represented by a single sector in Hyperspace.
In order to enter or leave Hyperspace, you Warp.
Warppoints to/from Hyperspace are liberally distributed around the edge of all starsystems (12 per system) in addition to the standard warppoints created by a "Not all connected" random map.

Hyperspace exerts a random movement effect on all objects.

The effects, in terms of gameplay are as follows:
1) A ship with Two (2) movement points can warp from one side of a system to the other.
2) Ships with only 1 MP are generally stranded in Hyperspace, and can only escape if the random movement pulls them over top of a known warppoint.
3) Warppoint Blockades are generally useless. With at least 12 entrances per system, the defenders are much too spread out to be effective.
4) Blockades on the Hyperspace side of the system's warppoints is difficult at best, due to the random movement.
5) AIs cannot play this map. Ship pathing is restricted to in-system only. Presumably this is due to the extreme numbers of warppoints per system. The key is to have line of sight to the ship's next order location. You cannot tell it to move across the empire, but you can tell it to warp here, then warp to the next system, then warp through to the next system.

The map does a decent job of simulating B5, StarTrek, and StarWars movement at FTL speeds between starsystems.
