The direction of the mod post-1.3 is going to be based on adding large and important structures that work similar to dungeons. Each will have an interesting back story. Current inspirations are:
Hypixel Skyblock Dungeons
When Dungeons Arise

However, we want to be distinct.

Pros of HPSBD:

• Grind-like experience
• Goal is to get rare loot, has multiple difficulties
• Interesting and powerful mobs
  Pros of WDA:
• Great and inspiring outside
• Interesting thought given to each structure
• Expert-level dungeon

Mo' Structures Principles:

• All-purpose structures that fit well into any modpack
• Good quality
• Interesting lore and backstory
• Server sided

Current problems with MoS is that our structures can get old and repetitive, and the current goal of adding too many might not work out as we want them to. Furthermore, our current structures can be small and lackluster.
Therefore,
1.3.0 has a goal of recreating some of the current concepts. Air balloons will become a fleet of air balloons with important lore and information. A few main balloon ships could even have built-in houses with lore and mini-dungeons. Smaller air balloons might contain loot. A new sky castle might even contain a village, but ideas are WIP.
1.4.0 will be based around adding new structures.
Dungeons will likely go here. We need our own direction with them, as well as make sure we are adding great value to modded survivals. WIP.

Possible Research Projects:
What is something that players need? And could this need be backed up by RPG without ruining balancing?
How can variants bring new experiences to players?
How can we keep a cohesive narrative, theme, and symbols?
How can we add puzzles that make the player think?

Comments and ideas are appreciated.
