Actually, I requested to purchase Ontario for the Liberty Rogues (although i would be happy with Yukon or Alberta), but I can see that Unselie's idea makes far better sense and would massively increase the RP etc.
LSF, go get Minnesota, Quebec, New Hampshire etc or remod illinois (I know it's an LPI system but so? i'm sure there wouldn't be any objection to liberty forces modding it). Leave the Ontario system open for smugglers/pirates/neutrals etc.
So anyway, to recap. I personally think we should go with Unselie's plan. I think that would make things far more interesting, and it certainly wouldn't possibly detract from Disco whatsoever, merely enhance it. Ontario is a highly useful side route for getting to NY from the north or just plain getting to Colorado, so it would always be used by a considerable amount of people.
It would be nice to see Ontario/Alberta/Yukon being slowly developed over a few mod updates and RP could be done along the way between the various factions interested in grabbing real estate in the area (the Rogues would certainly be moving into the area, especially Yukon as it is directly adjacent to their guard system. The Hackers and Xenos wouldn't be far behind either).
