If you have an indoor weekend coming up, the excellent Cities: Skylines. The game is free to try on Steam for the next few days, and if you like it (and you probably will), the base game is a whopping 80% off at $6 / £4.60 / A$8.60.

Of course, there are plenty of paid expansions available, and this free period coincides with the release of Sunset Harbor, which adds an all-new fishery with micromanagement; Fraser tried this expansion earlier this week and found that the fishery did not do well in the desert wastelands and He found it to be a struggle. But don't let that discourage you.

The new expansion also adds five new maps with different climates (one of which is the aforementioned desert) and has a new bus system and passenger helicopter service. You can read more about the expansion here. If you want to know why you should try Cities: Cities:Skylines, watch the 25-minute disaster film set in the game or witness Chris' frankly terrifying Blimp-opocalypse.
