Factorio Forums

I was thinking of making an AMA thread for the developers of Factorio so members of the community can ask them questions . i have a feeling ., like with my steam summer sale thread thiat this can quickly descend into madness so if it can be possible to only limit the users to posting questions and not giving options on the answers ,

So i guess i will start out...

What is your favorite part about developing Factorio , is it the coding , the coming up with the ideas , conversing with community. out of all you do in your day to day life of developing what wuld you rate number 1?
