HOW TO REMOVE 2K GAMES LAUNCHER:

1. Right click on game in Steam library
2. Select "Properties"
3. Under "Set Launch Options", enter the following command:

4. Make sure to change this file location to whatever drive you have the game saved on.
(If you want to find the correct location, select "Properties" on the game as before on Steam, then select "Local Files", then "Browse". This will show you the exact location of your game folder).

5. If you want DX12 version, change CivilizationVI.exe to CivilizationVI_DX12.exe

This solved the launcher issue for me, hopefully it can help others remove this annoying "feature".

To bypass 2K dumb and greedy launcher which causes crashing or fps problem:
Library -> Right click on Civilization VI -> Properties -> Advanced Launch Options box -> Insert this line

"C:\Program Files\Steam\SteamApps\common\Sid Meier's Civilization VI\Base\Binaries\Win64Steam\CivilizationVI.exe" %command%

(Note: the line is Steam folder by default, if you change your Steam folder location, customize the line to your Steam folder location; if you want to play the game with DX12, change CivilizationVI.exe to CivilizationVI_DX12.exe)

I have played Civ right from the start and every upgrade is a step further to fun love the challenges and I am 71 so if I can do it anyone can

I'm an old man & I use this game, (Single Player), to help me to focus on multiple issues at the same time. I still don't know what the "Scout" icon with the "heart" in it is supposed to mean because I can't find it defined anywhere but that is the lease of my problems. It has helped immensely with my memory and I find it relaxing.

Civilization, for me is remembering sitting next to my dad for hours and hours and him trying to explain it to me but my little brain not understanding it. For this I will always have and play this game, Thank you Dad, miss you very much....

Whichever employee worked on fixing over 300 UI bugs (25% of UI bug count) using Lua language, Jira software, and Perforce version-control system, I bet he was a pretty killer dude!

I enjoy playing alone.

"I can quit any time I want."

I used to enjoy this game and civ 5 but i would strongly advise not to purchase with the current EULA it was updated a few months back and is now a disgraceful piece of spyware.
In short the publishers of this game are granting themselves full permission to your personal information, nothing seems to be off limits then they go on to state how they will then distribute your personal information to anyone and everyone who wants it including countries with poor privacy protection records! (yes it actually states that)
Found half way down the Terms and conditions under INFORMATION COLLECTION & USAGE is this gem of a passage.
Here is a copy and paste of that section in it full glory.

INFORMATION COLLECTION & USAGE

By installing and using the Software, you consent to the information collection and usage terms set forth in this section and Licensor's Privacy Policy, including (where applicable) (i) the transfer of any personal information and other information to Licensor, its affiliates, vendors, and business partners, and to certain other third parties, such as governmental authorities, in the U.S. and other countries located outside Europe or your home country, including countries that may have lower standards of privacy protection; (ii) the public display of your data, such as identification of your user-created content or displaying your scores, ranking, achievements, and other gameplay data on websites and other platforms; (iii) the sharing of your gameplay data with hardware manufacturers, platform hosts, and Licensor's marketing partners; and (iv) other uses and disclosures of your personal information or other information as specified in the above-referenced Privacy Policy, as amended from time to time. If you do not want your information used or shared in this manner, then you should not use the Software.
END QUOTE

As you can see not your usual EULA the licensor recommends not using the spyware sorry i meant software, if you do not want your data collected and distributed in this way, good advice.

New EULA:
"The information we collect may include personal information such as your first and/or last name, e-mail address, phone number, photo, mailing address, geolocation, or payment information. In addition, we may collect your age, gender, date of birth, zip code, hardware configuration, console ID, software products played, survey data, purchases, IP address and the systems you have played on. We may combine the information with your personal information and across other computers or devices that you may use."

This is terrible. I was actually coming around to buying the expansion, but this definitely puts the break on that choice. I'm uninstalling this game for the time being and I recommend you do the same. I have zero tolerance for companies who pull this sort of stunt on its customer/fan base.
