I can get the .are files sorted but the question that needs to be answered first is which maps. So for me, it's not simply a matter of getting something like a cave map completely done because the map might be something like a city map. I'll need to know what people want first before being too presumptuous about it. Not to mention that if people want a map to have terrain changes or other alterations, I would need to know exactly what before preparing it.
Yeah, I figured that if I was to prepare 10 maps in the above plan that there would be a big possibility of a project becoming dead or unfinished. But I figure that if I could get them all sorted with .are files and maybe monster spawns that would be a pretty big development. Especially when ToB already has a number of detail quests, that all it is really missing is regions in the style of BG1 that "pad" out the world map. They probably wouldn't even need their own quests but rather just townspeople NPCs and shopkeepers to make the areas come to life at the very least.
For example the bare idea would be the following.
Survale Ford - Just a regular plains map with regular enemies
Gorge of the Fallen Idol - A series of caves full of orcs and goblins
Myth Dyraalis - A town of gnomes and elves
Myth Unnohyr - A forest map that causes a wild magic zone during the day, dead magic zone during the night (Possible underground dungeon)
Magis Tor - A tower complex that is impossible to enter without a "key"
Barakmordin - A giant fortified church that acts like BG1's temple map
Ithal Road - A crossroads map
Darromar - A big city that could be closed off to the player via the city gate (Could be opened if quest modders want it)
Shoonach - A desert map and temple with undead enemies
Minthrux Vale - A mountain map with beholder and illithid enemies (With the possibility of a dungeon called Shangalar's Pyramid)
So mostly they'd just be "filler" maps that pad out the regions. So for example to get to Agazigal's Lair, you'd have to pass through a mountain map full of beholders instead of just teleporting there. Something like Barakmordin or Myth Dyraalis could be void of quests but simply just be there to replace Saradush as a rest map. The rest could just be dungeons that contain treasure at the end of them.
If someone wanted to add a quest, then all it would take is for a door to be unlocked or a portal to be added to the map. I could get this "world" sorted myself and leave the possibility of quests being added for anyone who wants to contribute. So if they want to make a quest around the mage towers of Magis Tor, then the key could be added and the region could be unlocked for the modder to play with. But if no quest modders decide to contribute then at least there will be extra regions with monsters there for ToB.
To me that seems like the most pragmatic way to approach this. For me to build up the canvas for modders to work with, and if they don't then there would be still alot to do with the maps. Even if it is just slaying beholders and undead. So it would be a relay, where I build up all the foundations, then a quest modder contributes a quest or some background NPCs, then another, then another. And when it does eventually stop, then there would be at least something at the end of it all. I'm not really into the idea of creating a mod with intricate questlines with their own party members that require long term planning or dedication, but just creating something that augments ToB and helps to fill in gaps in the worldmap. Where the quests are really just a couple of throw away lines with maybe a boss at the end of it, ToB could use some of that since it already has enough dialogue heavy quests.
Idk, does this sound reasonable? If so then I could get to work converting the above 10 regions to .are files and have them done in probably two months from now. From there if quest modders want to contribute short quests or content then they could do so. With most of the foundation work done, I'll then go on standby mode ready to help those quest modders with alterations or additions to the maps.
