It’s sometimes enlightening to read through the Steam Top Sellers list. While you’ll see your mega-budget AAA hits in the top slots more often than not, it’s far from unusual to see something like Train Sim World’s newly released DLC - The Great Western Express - sitting in the top 10, proving that PC gaming is broader than you might expect, and that your own definition of ‘mainstream’ might need expanding too.

The PC is host to the best and boldest simulations around. Trains a little too pedestrian for you? Check out some other options here.

Offering a uniquely British set of scenarios, the Great Western Express pack focuses on running busy passenger trains in and out of Paddington station and across the Intercity express line. For those really wanting to commit to the simulation, there’s the new Service Mode, allowing you to experience life as a train driver working to a precise 24-hour timetable. While not quite as thrilling as a Battle Royale mode (although I do wonder how that would work with trains), it’s an interesting immersive hook for the expansion.
