The AI tells me that I'll need metal bars, so I immediately start building a couple of metal bar buildings, which ate my only fabricator. The buildings didn't complete, so there was no way to progress. This tutorial screen comes *after* the AI message. While I eventually figured it out, it was not a fun experience. Maybe don't tell the player they'll need iron bars except on the *same* screen as telling them to slot the fabricator.
Having played many factory games, the moment I saw "iron bars" I jumped in and started building "the iron bar building", as one des in factory games.
