A very comfy, casual little city builder with massive, glaring issues that will likely never be fixed. I've been playing since the game entered early access and I can confidently say that it still needs some serious TLC. It doesn't run very good, despite the simple graphics, and it makes my computer sound like a jet turbine at medium settings. The ui is better than it was, but it still feels weird. All the custom building are very cool, and I wish more of these games had this level of freedom, I only wish this game did more of that. Not having direct control of where homes are built is weird and the system feels like it belongs in a different game.

Absolutely LOVE this game. It's relaxing, as challenging as you want it to be, highly customizable, and completely addictive. What a great game!

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.
