Finding beautiful landscapes. In VS we have many since 1.9. I love that;
Rare loot: pumpkin seeds, cabbage seeds, rare vessels, rare paintings;
Stone types: after I get comfortable with food and metals, I start to look for different stone types to make custom buildings, or even to choose another place to build with a theme.
Trees; animals; different food (I'll be very happy when fruit trees come into the game);
To find translocators: that's fairly new, but it helps a lot to reach new destinations or shorten some way. Very much useful since we don't have fast transport means right now.
Different types of ruins;
Traders so we can get rare items, clothing or resources.
