even then, in se5 you need to know where a system IS before you can open a warp point there.
in se4 you knew the locations of the systems from the begining of the game, so that was not a problem
The old system was better both for realism and functionality. Any race with technology even close to the ability to travel through space (let alone opening warp points) should be able to make a reasonably accurate star-chart of thier immediate vicinity. But not so in SE5. I could understand if there was a tech area to enable this, but there isn't even that.
Anyone know if this is something that can be switched on in the settings?
SE5's system could've also used the fog of war allowing you to see all systems in a certain radius, but at the same time allow people to create facilities for dedicated stellar observation.
