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 BUT You don't want this version, its been superseded by: Interplanetary Enhanced Edition https://store.steampowered.com/app/650220/Interplanetary_Enhanced_Edition/

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…

Games like Dying Light, where nightfall changes the rules

Games like Dying Light are easy to find if you only want parkour or only want zombies. These eight keep the part that matters: a city that becomes a different place after dark.

Games like Portal 2, where one idea carries the whole game

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.

Toxic Commando Game Pass: subscribe, or buy the key?

The Toxic Commando Game Pass add landed on 12 November. Our price record since late September shows the key route barely moved, which changes what a subscription is worth.

Titanfall 2's campaign changed its own rules every mission. Games like Titanfall 2 that keep one part of it — the wall-running, the mech, or a campaign that never settles.

Games like Frostpunk for anyone who misses the Book of Laws more than the cold: the sequel's factions, a besieged house, beaver droughts, a drifting ark and the template it came from.
