Paradox Interactive's Cities Skylines recently got a new DLC pack, Sunset Harbor, and the game is enjoying a hefty discount along with a free weekend to boot.
Cities Skylines lets players simulate building their own city, with all the nice weather and fancy infrastructure which is the polar opposite of the steam-centric Frostpunk from 11-bit studios.
In case you are not sure it's your cup of tea, you can give the game a spin for free on Steam until 30 March 2020. If it turns out to indeed be your cup of tea, you can pick the game up for $5.99 / €5.59. That amounts to an 80 per cent discount which will end at the same time as the free weekend.
Keep in mind that this is still a game published by Paradox Interactive, which more often than not means that a ton of DLC is going to be present. With Cities Skylines, this is the case and the DLC alone amounts to over 100 USD or EUR in case you choose to buy it. Then again, there is nothing stopping you from enjoying the vanilla game or just add a DLC pack or two of your choosing.
The city building simulator is not hard on PCs either and even rigs as old as half a decade or more can run it. In fact, the game doesn't even require a quad-core CPU. Storage space required is small enough to easily fit on a USB as just 4GB will suffice.
To try the game out for free, you can just go to Cities Skylines Steam page and click the "Play Game" button. The download itself shouldn't be long so it's not exactly a waste of time even if you don't like the game enough to buy it.
