In the new DLC for X3: Terran Conflict, are there any changes to the overall layout of the universe in terms of gate connections or neighboring sector placement?
CBJ, a big boy at Egosoft, has posted here a pretty lengthy guide detailing the new features of Albion Prelude. It is a good read, and has made me consider pausing Skyrim (blasphemous!). However, he only has this to say about the new map:
Albion is a key area of space that will feature heavily in X Rebirth. You can get your first glimpses of Albion in X3: Albion Prelude, and see emerging signs of the momentous changes that new technology will bring to the X Universe. Look out for the corporations that are driving this new technology and vying for control of the new sectors and the valuable resources they contain.
The X Universe is a dynamic place, and even in the short time since X3: Terran Conflict some things have changed. New space has been discovered, control of some sectors has been lost by the people who once lived there, and in a few cases gates have mysteriously shut down cutting off routes that were once busy thoroughfares. We won't be spoiling the fun for explorers, however, by giving precise details about what has changed!
And I found a quick 'initial-glance' list from EmperorJon
Universe Changes -
Many of your familiar Unknown Sectors have been claimed. Some more have appeared. The North East of the universe is different! Zyarth's Dominion no longer links to Ocean of Fantasy, the Split sector in between them is GONE! It's a dead end Split area up there. Sector descriptions suggest they're trapped and the gates are beginning to fail as the Xenon advance. Bluish Snout now links to 4 of the "player sectors". Xenon Core 023 now links through to Xenon sectors connected to Aldrin! So Heretic's End isn't the ONLY way to the Solar System... Wink Harmony of Perpetuity is included, and owned by the Goners.
It is definitely a big improvement on TC, and should certainly give fun until TNBT comes along.
To quote Gazz, the legendary author of MARS and many other scripts:
No revolution but a lot of evolution. =)
EDIT: And you can now have a balance of 2,000,000,000,000,000,000 credits, not 2B :D
