Walk in, talk, leave, and come back later. The people you meet remember you.
Click (or tap) the building and your character walks there. When you arrive, the building's card appears with the people inside. Choose Enter, or press E.
You can only enter once you're standing close to the building, so if Enter is missing, click the building to walk over first.
The interior fills the screen and everyone present sits in the row of portraits at the bottom.
You speak first. People don't open the conversation when you walk in. The exception is Story Moments, where you walk in on something already happening.
Nothing is scripted. Each reply comes from the character's profile, the place they're in, what they know about the world, and what they remember about you.
Choose Leave, or press Esc.
When you leave, each person who took part forms a memory of the conversation, and their feelings toward you may shift a little. Next time you visit, they'll remember what happened, and they'll know your name if you gave it. That's the heart of RPBuddy.
