Castles are built a lot faster before patch 1.0c (150s instead of 200s)! So using AoK/AoC 1.0 for a level like this is very significant. You can't use Voobly to run any version other than patch 1.0c of course, so no widescreen, but it's a good trade-off. There is also a 1.0 patch mod but I'd rather not to use it. AoK don't have Bloodlines or auto-assigned villagers after finishing drop-off buildings, so I patched my game back to AoC 1.0.
