When I started up Railways of Love I was taken aback by the game's old-school graphics. Then, on my first playthrough, it didn't feel very interactive to me. There were only a few times I was provided a choice that would affect the story of protagonists Abel and Juna on their train ride, and most of the actions I could select were actions like "The attendant comes by" or "The light blinks" - actions that Able and Juna couldn't take for themselves. The primary exception was that each time I was given a choice one of the options was for Abel or Juna to confess their love. However, when I tried to select that option, Abel or Juna always found an excuse not to confess their love, and the game forced me to select another option. So it wasn't clear to me who I, the player, was supposed to be. The author of their story, I suppose, but an author with some rather severe restrictions on the story I was writing. I wasn't that impressed at first.
But then at the end of the story the game encourages you to play again and try to change Abel's and Juna's fates. The game was so short I thought I would try it. And here's where Railways of Love really starts getting interesting. You can replay the story multiple times, with each playthrough revealing more of Abel's and Juna's backgrounds and often giving you a different ending.
And these endings are not the kinds of endings you come to expect from a work with the word "love" in the title - if, like me, you're an American. This is not a game with a Hollywood-style "true love conquers all" sensibility. Railways of Love is more mature than that, displaying an understanding of what it means for two people to commit themselves to each other long-term and all of the costs to careers and other relationships that go along with that.
I found it beautiful and poignant.
So, my recommendation is: Don't stop with the first playthrough of Railways of Love. Don't even stop until you've seen all the endings.
