Alright!
We can continue this by e-mail, so just get in contact at will.
Me and Erkka are in, but for Finnish Museum of Games staff we need to ask with a bit more details about the topic.

Hey Flap, a pleasure to hear from you!
My reply is terribly late, but surely I'm into an interview if you still feel like it.
Best of luck with the project, and it's good to hear about this kind of things being worked on - here and there :)

Some projects do that but  we like to keep them separate, as some like Steam and some prefer any non-Steam way to get the game.  The players have specifically asked to provide non-steam distribution such as itch.
(Also, if there was a Steam key included the Itch price also would need to be higher, comparable to Steam price, to play fair with the past purchasers.)

Greeting from Finland!

The time has come for us to enter the realm of itch.io and let you all lose yourselves in the most intricate, detailed and enchanting iron-age game world as UnReal World is now available on itch.io.

https://enormous-elk.itch.io/unreal-world

UnReal World is a cult classic open-ended wilderness survival roguelike taking place in the ancient North long, long ago. It's the longest living roguelike of all times, first released in 1992, and continuosly being developed ever since. The latest release, from where our itch.io journey starts, is version 3.62 released in march 2020. So updates are something you can expect.

Throughout the years, UnReal World has been praised for its incredible depth, realism, atmosphere and immersion. The game world is rich with historical atmosphere in which northern folklore, knowledge and way of life play an important part. And well, it's no secret that the game world is actually based on the ancient Finland in the late Iron Age. If you are new to the game you may also find interesting that we have not only coded the game but also lived it to quite extent with experimenting, re-enacting and following the lifestyle of our ancestors. Just get in there, and you'll see.

Well, that's the game. And this is us.
