This is a pretty good turn based strategy - that mixes city / planet building with artillery "one salvo per turn" gameplay. BUT You don't want this version, its been superseded by: Interplanetary Enhanced Edition https://store.steampowered.com/app/650220/Interplanetary_Enhanced_Edition/

Note to self: skip it for the enhanced edition.

Not recommended Aug 1, 2024

I see why the Enhanced Edition exists now. Don't get me wrong the game isn't bad and it has one or two things thats a lie only one thing that I enjoy compared to the Enhanced Edition. Sadly its not a major thing so... Enhanced Edition truly is enhanced. +Even though Enhanced Edition is cool and fun one thing that somewhat bothered me was that you never really got to see the impacts of whatever projectile was being thrown at a planet. You could definitely see them flying through space and hitting ♥♥♥♥ but it was really hard and just not really worth it to try and catch the moment of actual impact. Well in here you can! The camera settings are a bit different and they're mainly worse I'd say but thanks to that with some luck you can actually see the projectiles impacting a planet from up close. It looks pretty damn good. -Enhanced Edition looks better. -Enhanced Edition not only looks better graphically but it looks better UI wise too. Its still the same like the core is the same but Enhanced Edition, it should be obvious from the name, offers a few little enhancements that makes things a little faster and a little more beautiful compared to this one. Especially the tech tree Enhan…
