Hi!
My apologies for the short notice, but if you want to ask someone who's crazy enough to make a game in the same category as RimWorld anything, well, I'd be happy to answer your questions on reddit :)
It doesn't have to be on the game itself, questions about steam and development in general are welcome too!
In any case it will happen on r/Steam at 1PM PT (pacific time), which is around 4PM US Eastern, 9PM in the UK, and 10PM in western Europe - click here to view the time we will be live in your local timezone.
This post will be updated with the proper URL when it becomes available. It will be on the r/Steam subreddit.
Edit: our Reddit AMA is happening here, feel free to join :)
