Stardeus is a colony building sim set in space, where you build up your own spaceship to go off exploring and survive.
The developer just put it up for a Steam Free Weekend, so you can download and try the full game entirely free for a few days. If you decide you like it, the game is also on sale with a 50% discount until June 19th. That's the biggest discount it has had to date!
Competition is hot though, with RimWorld - Odyssey just being announced that does a very similar thing but there's still a lot of differences between them. I guess this done mean I can't call it RimWorld in space anymore then.
Stardeus is much more expansive for the space side of things because that is its focus. Stardeus also added ship to ship combat in an update released back in May.
The basics:
- Build a Spaceship - In Stardeus you will build functional spaceships and space bases that will actually fly.
- Establish a Colony - In addition to robotic workers that you control, there will be a human colony that you will have to take care of. Or will you?
- Explore the Universe - Fly your spaceship and take your colony to the unknown depths of a vast procedurally generated Universe.
Still, I should try it again sometime soon and check out all the new systems.
