I’ve grown up with this game, and have spent many fun hours building my railway. I don’t play as much as I used to (since I’m trying to improve my screen time), but I still it.
Despite my expansions I’ve kept my first two locomotives (a red and a blue steamer) running on my first two lines. It’s not efficient, but seeing them still doing their little runs after more than 8 years is just really fun.
It is a “freemium” app (as so many are today), but everything is done tastefully. In game currency can be purchased but is also generated naturally with gameplay. Adverts are present, but in the form of an optional button you can press occasionally to generate the same in game currency. No obnoxious forced ad viewing or anything like that.
It’s fun, it’s wholesome, and it’s suitable for kids & older people alike. All in all, one of the best games I’ve ever played.
