Some never flatten any land, while others won't even start until a huge swath is flattened. Some are extremely meticulous about how they place buildings and modules, while others slap them anywhere. Some build a farm first thing, others... forget to build one until they're out of food. Most common probably is taking some time to realize building more than one workbench/module per shop is a good idea. It does take quite some time to get to the mid-game this way, but that's okay. I always get excited for them when a creepy event pops up.
