Having played a bunch with the first few builds of asset forge, I have a bunch of thoughts and feedback I'd like to voice; as well as to hear other people's ideas. From me, basically all positive, especially considering the early stage we're at. 

Even with a pretty small amount of collections at hand, the system feels flexible. The ability to freely add your own models will make this super powerful, and I look forward to seeing the new systems for browsing collections that Kenney has discussed. 

Having some tools greyed out, like a free transform and advanced texturing, is a good way to see whats coming in future updates. It also stops me complaining that they aren't there, because when they are this will really open up ; I sincerely look forward to it

I think it's a really fun tool that fits nicely into two unfilled (as far as I'm aware) roles :

1) Beginners / Lone programmers
It bridges the gaps between using free/open-source assets, and building things yourself.
Usually it's quite hard to find free assets that you can spin into something of your own - and this will make it a whole lot easier.
As a lone programmer with art experience, I can see myself using this a lot when I just want basic assets for layout. 

2) Small Studios / Indie Teams
It makes it far more possible to spread the load of art creation around a small team. 
By creating some smaller modular prefabs, team members with little to no experience in 3D software could start assembling models. 
I'm excited to see if gets picked up in this way, I'd love for something to fill this role. 

Interested to hear how everyone plans to use it!
