Playing as recent arrival Lena, your challenges include learning a new language and uncovering family secrets – its developer hopes it will spread ‘a little more compassion’

The cosy house-sorting sim has become a much-loved staple of the PC indie scene. Titles such as Unpacking, A Little to the Left and Momento charm players with their detailed interiors and quiet narratives of lives lived and shared within the same four walls. For Clean Start, Polish developer Serious Sim has taken a different approach – here you play as domestic cleaner, Lena, an immigrant who has arrived in an unspecified western country with little knowledge of the local language, and a family to support back home.

From here, you’re tasked with cleaning a series of houses and apartments, polishing tables, tidying shelves and scrubbing muddy pawprints from kitchen floors. It seems you’re able to rearrange the rooms, giving them a personal feel, which is after all one of the most pleasing elements of the genre. You can also, we are reassured, pet the dog.

Hidden gems can be unearthed, but you have to dig deep into the bargain bins of countless outdated Fifas, Wii Fits without the controllers and partially finished quizshow games

As an eternally optimistic charity shop fan, I hold on to the fantasy that one day I’ll walk into my local Oxfam and find a pristine copy of the Sega Saturn shooter Burning Rangers for £1.50. Or perhaps a box full of old Neo Geo carts for a quid each. Sadly, this is now unlikely. Charity shops have caught on to the fact that old video games – like old vinyl albums – are highly collectible, and so they’re putting the good stuff on eBay. That’s fine, it’s their job to raise money, not to provide opportunist swine like me with bargains. But what games can you find tucked away in your local branch of Barnardo’s? To find out I visited about 40 charity stores across the country. Here is what I discovered on the shelves … And please do share your own charity shop gaming finds in the comments!

Deep underground the player joins a colony of ruthlessly exploited pit workers who could be taking on the bosses. How things play out will depend on you

It is rare for video games to feature industrial action as a key theme, but it does happen. There’s the shady Dockworker’s Union in Disco Elysium and the Orbital Workers Union in space adventure Tacoma; then there is Lynx, the evil union-bashing corp in Hardspace: Shipbreaker. Soon we can add A Line Held Tight, a visual novel that puts workers’ rights – and workers’ lives – at the very centre of the narrative.

In the distant future, a colony of miners digs far beneath the surface of an isolated planet, searching for veins of some exotic ore, protected from the poisonous atmosphere within giant mech suits. But the working conditions are woeful and as a strike looms, an unpopular employee named the Canary must decide whether or not to stand with colleagues and fight against suppression. The player, of course, takes on the role of the Canary, navigating personal as well as political struggles in a world rendered in stark monochrome.
