At least consider it when/if you are making another normal shard. Use the 4x4 or 6x6 sectors in the middle for this purpose. Make the area restricted with natural walls and disallow spawning in the rooms. Increase the number/values of sources, and make it accessible only by a new type of portal.
My main concern still stands, the world is kind of boring. A SE-sector on shard1 and a NW-sector on shard 2 is basically the same thing. Don't get me wrong, I've got a todo-list longer than I want to admit, but I feel like I've tackled most of the big things. I also think there's others who feel the same way.
Combat code can always be evolved further, and SWC has been a great motivator for many, me included. On the MMO-server however, there's little reason for me and many others to further develop it, unless we participate in war games or just plain destruction.
There's enough space for anyone with at least decent combat code to wipe out some newer players around you for new rooms. There's no reason to attack some of the more established people, except reasons stated in the last paragraph.
What I want to see is an area that is more desirable than the average room/sector, where you need top notch combat code to establish yourself and hold on to the rooms. Maybe a big alliance will just take all of the new space, but that's fine. Maybe it will not be very many who are able to try to establish themselves, but it can be a showroom for advanced to combat tactics and a place for "world news".
I still feel that this adds a lot of new "game content" without taking much development time or make the game any more complex. It makes the world more interesting, and it can be a motivation for both new and more established players.
