Hello,
As my birthday is drawing near, I uploaded to Nexus a 'teaser' mod for my project concept. This is a good oportunity to jump in!
http://www.nexusmods.com/skyrim/mods/55704/?
Essentially, I wanted a backstory that would ease the difficulty curve associated with making a non-trivial quest mod. So,
- no new landmass introduced - prefer to reuse existing Skyrim locations (we may end up inventing better tools to manage conflicts, though).
- lessen the urge for voice acting - for instance, by developing the questlines with dialogues in a tribe of talking giants.
Thus, the story is loosely based on Ragnarok myth. And the goal of the project is to enhance Skyrim with some hardcoe adventure-puzzle gameplay.
Having said that, such kind of modding project can be developed is relatively small steps, retaining consistency from one release to another. So I feel it's fine for other people to join. Myself, most likely I will focus on somewhat expositionary quests leading to the situation depicted in this teaser mod (that's where I'll have most fun at this stage of learning Creation Kit).
