Since I didn't feel like too much writing and scripting this past week, I focused on filling in the random overland map areas the party can visit. With all these being prefabs, the only work needed was placing monsters/treasure and the like. As a result, most are now ready for exploration, hacking and slashing. A few small sidequests in there as well. Think of them like the areas off the main path in BG.
A few prefabbed areas came prelinked/thematically related, and their design suggested some quests ideas that I haven't fleshed out yet. So those two areas are on the overland map and can be entered, but currently are empty.
Still to do:
a remote desert oasis town on the edge of faerun needs more population besides it's current lone merchant. ditto for a town in the far north. Both these areas are just quick stops on the overland map, so they don't need to be extensively filled in, a few more merchants and some random commoners would do. They are just pit stops for players to sell loot or restock.
The town where the players stronghold is needs to be developed. There will be 3-4 quests here as well involving the players interaction with the current powers of the town. The stronghold itself is built but needs to be filled in more, and the generic stronghold system conversations need to be converted to campaign specific ones.
Another town is complete, but was a prefab set outside faerun. The lore and conversations needs to be converted to Faerun lore/conversations. As it's the location of one quest mcguffin, it needs to have more quests put into place other than the single current quest leading to the mcguffin. Fortunately, the built in conversations for the area suggest several quest hooks, so I only have to fill them in and give them an evil spin.
Companion conversations about quests are almost all written (8 companions x the number of quests, plus many have different things to say depending on the quest state = lots of work). They still need to be able to say what they think of each other and important npc's. Then the conversations need to be moved into the toolset. Their interjections into pc conversations need to be added in many cases, and their "flavor" conversations for different areas have to be done. Currently they are silent SoZ party creation type companions.
Seems like a lot remains, but filling out the overland areas seems like a hilltop and completion and the beginning of testing now seems downhill.
