Baaaaaaaaaaaaaaaaah.  

Help cannot find out how to download mods not in the metaverse

Some people are holding off because it's likely the file structures are still subject to change until workshop integration is complete. It may be annoying to adapt a mod that's built one way to a new system. It doesn't bother me though really.

As for faction mods and the like, they're actually kinda annoying to make right now - perhaps people are hoping that it will become easier with the workshop.

Is the workshop already open for GC3 on steam?  I been seeing updates from steam community stating "X new items in workshop this week", but when I go to workshop and look for GC3, I find nothing.  I'm COMPLETELY new to this, so it could be something quite trivial.

This is a big one I'd imagine in a lot of people eyes. Any mods that change the behaviour of the game, rather than simply adding new content, require a total conversion. Not only will this cause problems for people wanting to combine multiple mods, each time the game is updated it will require every single change to be re-evaluated. You might see more available when updates to the game slow down.

It's twofold.

Firstly, as most have mentioned, it's likely to break existing mods when it's integrated. This is a pain in the backside as a modder, because you want to be working on the cool ideas that inspired the mod rather than wading through boring busy-work getting the bloody thing back to how it was last week. This is compounded by the fact that the base game is currently undergoing massive balance changes and has huge issues, which means that many mods will either become completely unnecessary or will need heavily re-writing every week or so; once the workshop is integrated SD will probably calm down a bit on the major shifts.

Secondly, the present 'market' for mods is very small, because many players don't come here. They'll maybe look on the Steam forum, but won't look for or find this site. The Workshop provides a one-stop-shop for hosting your mod where people will actually locate and download it. 

Well, I'm going to wait and let other people download mods and let them post their thoughts.  Over time the best will come to the top.  Much better to let OTHERS be the guinea pigs.  

Plus those that have tested the trial 1.1 version are reporting it has quite a few bugs/problems that's why I haven't tried it because of the continual nerfing and new bugs and that's why I'm waiting for the full 1.1

On another note I'm having a great time learning to model in blender, you see I though even though I need to produce 2D art assets for my factions it would be best to model and render them through blender to get good shading, texturing and lighting effects and it means if they add proper video support for mods I can rig and animate them too.
