Although I appreciate people's concern, as I said in my original post, the publisher deal is just a marketing deal. I don't have time or expertise to market the game properly and it'd be dumb to release an expensive game without trying to market it properly.
The publishers aren't giving us any signficant sums of money (if anything at all) and there's nothing in any of the potential publishing deals that means we lose control over the design of the game, have to change the schedule of the game, be forced onto the Epic store, discontinue Community Edition, etc. We're just going to get a marketing partner to make sure everyone knows that Xenonauts 2 exists and what cool features it has rather than have it immediately fade into obscurity when it launches.
Please don't extrapolate too much about what that means for Xenonauts 2 based on your own perceptions of what a publisher is / does, as the reality is that publishers can do very different things depending on what point they get involved in a project and how much money they put in. Generally they have a lot of control over a project but if they come in near the end and aren't putting any money in then they're facing much less risk themselves, and need much less control as a result.
