Apparently it's because of this. At least that's the reason CO gave in the Paradox forum :D

I'm tempted to buy it, but with no official word that they're going to be releasing the Linux version anytime soon, I'm definitely not buying it.

I probably shouldn't buy it anyways as this looks like a massive time-sink game, but it does look tempting.

Always nice to see when a developer shows what can be done even with small amounts of data. Just because most of us have faster connections and bigger data storage devices these days, doesn't mean we should waste either of it unnecessarily. ( "Here, have this completely uncompressed 10GB patch, full of junk data, to fix some minor issues with the game. TROLOLOL" )

As for the game, not really my cup of tea, but it looks like a good release for those who like the genre.

Is the DLC really necessary for the game? How is the standalone version of Cities in Motion?

I'm not familiar with the game (because it's Steam-only and thus I won't buy it). Can mods be downloaded and installed independently of Steam Workshop (as with Skyrim)?

I don't see a Nexus subsite for the game...

It's fine, but some DLCs contain very useful vehicles, that could help you to play. Not really a cheat, but imagine your good well broke-in comfortable boots vs government issued that could be quite rough to your feet. In campaign mode these DLC vehicles could be your salvation, as they may represent vehicles with more room and faster speed than basic vehicles provided with core game. Whether this cheat or not, it's up to you.
Maps are just maps, some are interesting, some has own flavour (Japan, Russian, USA), some don't.

CiM2 IMHO is far more worse game in every aspect, outside of maybe more interesting weekly schedules.

Compared to others the DLCs from Paradox have a very high quality and add a lot of stuff to the game.

This is a good start! Perhaps Cities: Skylines, which is the most polished and the gold greatness of the series will show up here in this lifetime.

The 96Kb (yeah, kilobytes!) of .kkrieger does though!

Good going GOG. Just slow and steady bring more games here.

For Skylines.. well, Cities Skylines still updated frequently. At least 1 - 2 years before it can be considered as "complete" and be released here. So, just keep vote the wishlist first (if you haven't vote it) and... wait. Yeah. We can wait. We always wait anyway.

just go and download some mods. There were quite a few really well done vehicles by the modding community.
None of the DLC is really necessary.

I highly recommend the Vehicle Capacity Mod (I think it was version 5) hosted on CimX, as the default vehicle capacities aren't...well...that great. I also recommend the Ultimate Camera Control mod as it allowed a player to walk around (except for bridges) and ride his/her transit system in first-person, along with sprinting (with an energy bar) plus a wallet which fills with cash when your transit system has a profitable month, along with other options. You'll also discover animations and read messages on billboards and neon signs when playing in first-person view.

I've sunk almost 1,100 hours into the Steam version of CiM, way more than CiM 2 (which had great gameplay features such as the day-night cycle and timetables [that failed to account for NPC traffic] but was "cold and harsh" overall), but I'm STILL purchasing the CiM Collection here on GOG as a) other than Cities: Skylines I simply don't use Steam anymore, and with CiM releasing here on GOG Steam is now even LESS appealing), and b) I want my purchase to be a "thumbs-up" to Paradox Interactive (and of course Colossal Order and GOG) to mean "good job, guys, good job". Even better, the Steam version never came with the soundtrack, and I LIKE the music.

I'm wiped out from work so I won't have much time to play it tonight, but I'm BUYING. Cha-ching.

EDIT: The Schwebeban Mod (suspension rail transport) is also a REALLY well-done mod, also available via CimX. The capacities of the vehicles are small and non-varied, but are fun setting them up. I don't know if the mod devs fixed the bug where no more suspension rail vehicles were available after the year 2020 however, forcing players to use flying metro vehicles instead (I kid you not).

UPDATE: VERY IMPORTANT! - CimXchange is gone ( ;_; ), so forget references to the above. I have however managed to find one of the first Vehicle Capacity mods created from an European Cities in Motion fansite. Follow the instructions on the site for the Windows-based version.

If you're using a Mac (like me), install the .gs file in this manner:

1. In your Applications folder, right-click the Cities in Motion file and choose "show package contents"

2. In the Contents folder, double-click the Game folder and right-click the CitiesInMotion.app file. Choose "show package contents".

3. Double-click the Contents folder, then the MacOS folder. In this folder are several .gs files which list the vehicle packs, cities, et cetera. Drag the z_vehicleRealismModV#_#.gs file (the version on the European site turned out to be 3.2) into this folder where it'll join the rest of the .gs files.

4. Launch the game and enjoy the higher numbers of passengers able to board the vehicles (keep in mind that version 3.2 won't cover all of CiM's vehicles as the highest version I downloaded during my Steam days was version 5.5, but at least now the game won't be ridiculously hard when trying to earn income).

thats sad :/
however the german and the russian community seem still alive and well:

german one:

hopefully google translate is sufficent to navigate ;)
i don't know of any other english fansite comparable to CimXchange. (hopefully somebody backed up all the stuff before the site went down)

there is also a dedicated modding subforum in the official paradox forums where some mods where posted. But you can't access the forum, unless you join there and register your game.

Thank God, GOG didn't start selling the DLC single. Cities in Motion Collection is nice if you want a sandbox kind of game. The economic part is rather small. No comparison to Tycoon like games. But otherwise it is just a nice digital toy train/... set.

The base price is kind of high. The discount has to be at least 75-80% to make this a good offer.

Is anybody Bluish going to answer the questions about the Linux version? I'd kind of like to buy the game, but I need to know that the Linux version is still a possibility rather than being crippled by some impossible to fix bug.

As far as I know there is a Linux version of the game already, but I'm hesitant to buy the game without knowing that it's likely to show up eventually.
