Sounds very interesting....i am very excited
For all non german guys here i try to translate the linked post:
"Dear community,
I have been working for a long time on the problem of the cityboundaries with a friend of mine. Now That there is the offline-mode we have green light for the modification.
We've extended several Map-Terrain-Structures and aswell the Engine to our needs.
It has been a lot of work, but its done finally.
Our data is up to date and equivalent to the current SimCity version and should be compatible with all PC-Versions (including cities of tomorrow, digital deluxe etc.).
We will try to do our best to deliver the mod for every futute Patch.
A mac-version will be released a few weeks after the windows release. Another guy is responsible for that.
The .exe is not modified. Therefore is this modification neither illegal nor it conflicts with Maxis/EA's modding policies.
further informaition follow in a few days."
