Add to the list:
1] Rotational coordinate added to X,Y,Z so we can rotate exactly when placing.
2] Read out of coordinates when I play the map, i.e. tell me the X,Y,Z of where I am standing, so I can use it to place stuff exactly.
- Branching Conversatioins Leading to branching Storylines. That is probably a bigger feature.
- Branching Conversations to provide additional mission info or text without affecting the flow of the mission.
And a related element:
- Non-essential conversations. Simply said, just having some NPCs with a dialog that doesn't lead to any story advancement, purely for flavor and immersion.
There is a way to fake it with having them say just one thing, but we always NEED MOAR.
