The game also seems to be available on GOG.com, although at least one review says the Linux version there is much older than what's available on Steam, so perhaps the publisher doesn't care about non-Steam sales that much. > And you can't buy it outside of Steam, but I can't help it if the developer doesn't want my money directly. I've also heard of Cities in Motion and Railway Empire, though haven't played them myself. Mashinky () is an indie game that mostly focuses on trains, but also is in 3D and looks pretty good, like Transport Fever, though some people say that the economy in the game is a tad odd Simutrans () is another transport simulation game, which has a lot of different tilesets, but the actual gameplay of which seems to be a bit less enjoyable than that of OpenTTD and others, though it's also freeware Some other similar games that people might enjoy: That said, OpenTTD is also amazing because it's free, has a lot of lovely content and definitely provides plenty of replay value, in addition to not requiring a beefy computer (unlike the aforementioned game). The best game in the 'transport simulation' genre that i've played would probably be Transport Fever 2 ( ), because it not only looks better when compared to everything else out there, but the UI also feels really streamlined.
