Nuking would be unimaginable after five years on this game. As much as I'd like to rebuild Springfield all over again, the effort would be just too much. But I started with a strategy that worked out pretty well: after about five months of game play when I basically had most of the stuff then available (much less than we have today), I drew up a general city plan and moved everything around to fit the plan. Neighborhoods, parks, decorations, rivers, lakes, forests, everything. I've since built out organically, much like a real city grows. I have to say, it has worked pretty well. There are a few things I'd do differently if I had a chance to start over, but not nearly enough to make it worth it.
