I've always wanted a new type of dungeon keeper to come out, and being that it's kind of lost in the evilness that is ea, I doubt I will ever see it come to fruition. Either way though, I'd like to try my hand at remaking it in SC2. Pretty much I can see everything being possible with my current knowledge, except two things. One, digging and placing walls (one of the spells in DK2 if I recall was to put up a fake wall), and two, claiming land. The adding experience and such for training rooms, doing research, levels, etc, should be fairly easy I would think. Just the walls and claiming land would be the issue.
Any ideas on either one? I've not messed with terrain modification at all, so this would be quite useful to know.
