Well, I am pleased with the city devestating powers of N_O_Body's anitmatter power plant (though as I PM'd him it'd be nice if the blast radius extended to 40 tiles and fire radius to 200 tiles). However, I'd like a UDI mod airplane that had a bomb function that did the same thing. Say a B-29 or better yet, B-52 launchable from say the largest ingame airport class. Alternatively a nuclear missile strike mod disaster would be great fun for working out the "frustrations of mayor." Speaking of which, the existing meteor disaster doesn't have a wide enough blast zone for impact of an object its size, no where near realistic.
Just thought of one other mod that would work well in the next NAM. Streets should also be able to make neighbor connections. Right now in my agricultural empire I have to used road segments at the edge of my maps to connect my ag streets across town boundaries. Not realistic. Thanks people!
