CakeMC is a Minecraft server I run, and it first showed up in the development logs for Cake Launcher. It opened in August of this year and has since picked up a modest but real player base — the highest daily concurrent count has reached six or seven people. For a new server with almost no advertising, that's not bad at all. It has even attracted outside help: someone is now hosting a free panel server for it.
Before CakeMC
The server had an earlier life as RTMWorld, which is honestly a bit of a black mark in my history. It started as a private world I played on with a few friends. Then something happened, and it stopped running. It stayed dead until August.
Starting over
In August, my friend XieXiLin rented a VPS for two months and had it sitting idle. That gave me the push to try running a server again. I gritted my teeth, bought a domain, reorganized RTMWorld and renamed it CakeMC, with plans for two things: a RealTrainMod building server (which still carries the RTMWorld name) and a 1.17.1 survival server. Once everything was set up, XieXiLin and I posted a little about it in various QQ groups, and two or three people showed up.
How it grew
Tiansuo City and its metro
In early August, work began on Tiansuo City and its rail transit system, and it reached a reasonable scale. By mid-August the city itself had slowed to a crawl while the rail lines were moving noticeably faster. In late August, Lines 2 and 3 of the Tiansuo metro opened, and a POV ride along Line 3 went up on Bilibili as promotion.
The school year hits
September brought most players back to class, and the server settled into being empty most of the day. At the end of September the host expired, though the map had already been pulled out and saved. In early October, z0z0r4 stepped in to support CakeMC by providing RTMWorld with a free panel server.
Getting onto the server
The review group
First, join the external review group, fill in the questionnaire posted in the group announcement, and submit it for an administrator to check. Questionnaires aren't processed on weekdays — review happens on weekends and public holidays, and all day during winter and summer breaks.
If you have something you're proud of, such as an RTM addon pack or a build, send the admin a direct message with screenshots of your addon models or your build. If it meets the bar, you can get your review fast-tracked. Note that fast-tracking is not available during study time; wait for a weekend or public holiday.
Once you pass, an admin will contact you with the inner group number and the verification answer. Do not share either of them. Leaking the group number or the answer gets you removed from the inner group and barred from rejoining.
The client modpack
Download the client modpack from the inner group's files, put it wherever you like, and extract it. You'll end up with a folder containing the client files and a launcher.

Launching the game
PCL2 is the recommended launcher for the best experience, since HMCL is missing some of its features. Open the launcher and log in. If you own a legitimate account, we'd prefer you use it. PCL2 also displays server announcements on its right-hand side, which will become an important channel for things like modpack update notices. In the future the server will move to Blessing Skin Server plus the Yggdrasil API for authentication, to tighten player management.
Before starting the game, make sure the selected version is "CakeMC - RTMWorld" — otherwise you won't be able to connect.
Connecting
Launch the game and wait for the title screen. Click "Multiplayer," then add a server and enter the IP:
RTMWorld IP: rtmworld.cakemc.top
Save it, join, and start building.
