Cities: Skylines continues to grow and grow and become the kind of cult classic full featured city sim game that SimCity used to be back in the day. It’s already fairly nuanced and complex, but further patches continue to officially add more new features into it, even as mods unofficially take the game in unexpected directions.

The newest patch for the game – patch 1.10, which is also the first large patch that it has gotten – will be adding tunnels to the game. This is in addition to 72 European style buildings that will also be added (these buildings can only be used on a European biome, however).

While players will undoubtedly be thrilled at the news, the developers also confirmed a bit of bad news- compatibility with some mods has been broken, till such time as they are updated by their developers.

“We have worked hard to cause as few conflicts as possible with popular mods, yet this is a substantial update and with the code and functionality changes some issues have been impossible to avoid,” Finnish game developer Colossal Order said in a post on publisher Paradox’s forum. “Going forward we aim to find a solution where we can work with our core modders pre-launch to give them ample time to adjust their creations before the public have access.”

That’s fair, and good on them for recognizing the importance of mods to their game’s success too.

Back in the days predating Xbox, Microsoft used to have the best flight sim series on the market with its Flight Simulator series of video games. The series has largely lain dormant now for over a decade, but that hasn’t stopped old fans from yearning about, and wishing for a modern entry.

One of these fans decided to stop yearning and start doing- they took matters into their own hands and, with a user created mod for Paradox’s runaway hit Cities: Skylines, brought the classic franchise to the game.

It’s called Flight Cimulator, and it is available now through Cities: Skylines’ Steam Workshop page.

“What is this? A flight simulator inside a city builder? Yes! Follow your dreams,” the description reads.

The mod is still a work in progress, however, though we are promised more updates that will make it more authentic and realistic in the coming days.
