The terrains you mentioned were built back when the maximum number of bases was 64. Currently there can be up to 255 bases if you need them and the strat is in addition to that base count. I think you'll find that's plenty for a 256x map.
In order for strat bombing to have any impact, most people would use only one zone per country on smaller terrains but it makes for a boring map, and if you place your critical factories near the front lines, it’s too easy to cripple the countries. I like multiple zones but it really depends on whether they fit with your design.
Please Skuzzy, what is the maximum base count these days? Are we at 512 yet?
