One of the more promising factory games in development is the first-person blocky-open-world automation paradise of Foundry.  It's been in an alpha state for a couple of years now and available for players to get an early look at on itch.io.  Alpha testing isn't for everyone, being an earlier version than Steam's Early Access should be, but even so Foundry created a good following for itself thanks to a huge amount of content being released in stable and well-polished builds.  The paid version on itch.io is as much of the full game as is available at the moment while the free demo released back in September on Steam only goes up to a certain point in available tech.  Either one is a fair amount of game, and it's fairly likely that a player reaching the end of the demo is going to want in on the alpha.  Foundry is already a great factory game, letting you set up crazy-complicated systems from simple parts sprawling over a massive world extending endlessly in every direction, and that's even before taking into account the blocky terrain being fully destructible for extensive underground mining operations.  If you aren't in by the end of the month, however, Foundry's availability on both Steam and itch.io is about to disappear.

The reason for the change is that success brought with it publisher interest, and signing with a publisher necessitated a change in focus.  The work spent maintaining pubic-facing builds could be better spent on completing a proper Early Access release, so Foundry's alpha is no longer going to be available for purchase and the Steam demo is being pulled for now.  The expectation had been for a proper Early Access release in 2023, although whether that remains true is down to the fickle whims of the game development gods.  The plan is that experimental builds will be available for all itch.io buyers to test out and the next stable release is Early Access on Steam, and the specific time-frame of the stable build is dependent on feedback.  Even the publisher is as yet unannounced, so there's a lot of information forthcoming.  In the meantime, if you've got any interest at all in factory games now is the time to grab either the demo or the alpha (which does come with a Steam key when available) before they disappear on November 30.
