Paradox Development Studio and Paradox Interactive have today released their latest grand strategy game Imperator: Rome, as expected it's come with same-day Linux support.

Imperator: Rome is the newest grand strategy title from Paradox Development Studio. Set in the tumultuous centuries from Alexander’s Successor Empires in the East to the foundation of the Roman Empire, Imperator: Rome invites you to relive the pageantry and challenges of empire building in the classical era. Manage your population, keep an eye out for treachery, and keep faith with your gods.

Like with most grand strategy games from Paradox, there's a lot of mechanics you will need to learn before truly getting into it. To help with that, Paradox have a tutorial series ready for browsing over on YouTube.

GOG actually sent me a copy of it, although these types of strategy games aren't usually my cup I've given it a run. Imperator: Rome comes with a fancy looking launcher, allowing you to adjust things like fullscreen settings, resolution, picking which monitor to display on and language. A feature I tend to find quite useful as a multi-screen user:

However, clicking play on Ubuntu 19.04 seems to result in something not quite working right as the launcher quits and the game is nowhere to be seen. Trying to run the game directly, brings me the Imperator: Rome logo screen and then that too also quits to the desktop. I tried deleting the Launcher and Imperator folders in "/.local/share/Paradox Interactive/" (in case their account login system is overloaded) and now the game when launched directly gets me a tiny bit further to what looks like a loading screen, but then crashes to the desktop once again.

Our contributor Samsai, who also owns it from GOG is able to launch it. However, they've encountered other major problems like poor performance and "jittery" scrolling so it doesn't seem great there either. Samsai is using an AMD GPU and I have it confirmed from multiple others on an AMD GPU that it works, but others on NVIDIA like me it's not working for. So in this case, it seems specific to NVIDIA GPUs that it won't work.

Looking around, it seems there's a large amount of people having issues across all platforms. Some people like me can't run it at all, others that can like Samsai above are seeing major performance issues, others have it constantly crashing.

Paradox is one developer I am willing to give the benefit of a little extra time though, given their constant support for Linux with their strategy games. However, there's no getting around that this was a bad launch.

If you love huge strategy games you can find it on Humble Store, GOG and Steam.

Played yesterday for 2 or 3 hours. Launcher works, no problems at all with the game.

Specs: Linux Mint 19.1, AMD FX-6300 Six-Core, GTX 1070, 418 driver, Steam version.

Also have a GOG version, I think I’ll try it in the evening...

There must be some differences between how the GOG and Steam versions work then. You can see a post on GOG here with others having the same trouble as me.

I have a ticket with Paradox support, they're looking into it.

Quoting: SuperTuxUsing Steam had to use the workaround posted here:

https://steamcommunity.com/app/859580/discussions/0/1676938384244288207/

"Startup fix for Linux
The paradox launcher is failing to start with this error:
error [SteamService]: Failed to initialize Steam API: Error: Steam initialization failed. Steam is running,but steam_appid.txt is missing. Expected to find it in: /home/NOPE/.local/share/Steam/steamapps/common/ImperatorRome/launcher/steam_appid.txt

The fix is to run this from the terminal:
~/.local/share/Steam/steamapps/common/ImperatorRome/binaries/imperator
Which will launch the game directly.

Thank you flyinglama for this information."

Running great so far, other than the launcher issue.
You can also create the steam_appid.txt like this
$ echo 859580 > {install_dir}/launcher/steam_appid.txt

Thanks to Bluekkis from the paradox forums for this info
I still had to start the Launcher manually from the command line, but now it works as expected and multiplayer is active.

As Liam says in the article, it looks as if there are various bugs affecting all platforms, with some people being affected and some not. I'm not sure it matters whether you're on Linux or Windows, Steam or GoG, AMD or nVidia, or mega-rig or potato.
  • crash to desktop on launch
  • black screen on launch
  • stuck zoom level
  • stuttering on day change
  • stuttering on scrolling
  • hard lock-up in November


I'm getting bitten by the last one. I'm only seeing minor stuttering on my potato. The game looks awesome in the tutorial videos but I'd advise against purchase until it has been patched.

Quoting: liamdaweI wonder if it's an issue with a later NVIDIA driver or later GPU models then in that case. The 396 driver is pretty old now though...

FWIW, I've tried with the 418 driver and it is much worse. The game doesn't run from the Paradox Launcher. I have to go into the game binary directory and run LD_LIBRARY_PATH=. ./imperator to make it into the game. It still crashes in November, though.

Just tried that myself to see, same issue sadly:

Well, some evasive bugs here. Both Steam and GOG versions works for me. Don’t know why.

P. S. Interesting – Steam and GOG share saves and settings between each other. Most likely from .local/share/Paradox Interactive/Imperator.

P. P. S. I don’t have a paradox account, so no login in in launcher and multiplayer not tested. Well, it unlikely to influence anything…

Crash on startup, both on NVidia and AMD GPU (w/ Mesa driver for the latter).

Both systems use Debian Buster w/ KDE and French locale.

NVidia system has a GTX 1070 GPU w/ driver 410.104, AMD system has a Radeon 8790M GPU

I've noticed that my failed-launch crash dumps all have exceptions in network code from one of Paradox's libraries. If I disable my network card in Network Manager the game seems to launch from the launcher every time. Does that work on your machine?

Starts from the command line if I just run ./imperator on my NVidia box. However if I try to change the screen res it crashes (I tend to play in windowed mode).
