For those that might get burnt out of TGcodebase and end up liking the game, you can always try out other servers THAT AREN'T FURFAG INFESTED like:
CEV Eris: It doesn't deviate that much from the original SS13 formula, the main difference is that takes in a ship that has been refitted god-knows and changed hands for god-knowns how long. Maintenance is infested with oversized cockroaches and spider that will try to kill you, there's a fuckload of junk store in the maint tunnels from ages ago that stoaway vagabonds often dig through to find shit to sell or arm themselves with. There are antags like in regular ss13 and instead of being four departments working under the same NT banner, it's 5 different faction co-existing in the same ship that might or might not end up on they fucking up/killing each other off. They have their own discord server and are only up during weekends. It might contain a lot of jank-code.
NSV 13: Same SS13 formula, based off an old FTL13 codebase that was based off TGcode. Takes place on a ship that is tasked with a mission each round, this is granted because there are actual solar system maps and real time ship fights that might happen between NT fleets and Syndicate fleets. I don't really play it that much but it's neat and worth trying out. Like everything in BYOND, you might find jank but to a lesser extent
Interstation 12 - Warfare: Completly different to the normal SS13 experience, focused around TDM. There are two sides which are red and blue, based around a gritty and grimdark setting in planet somewhere in the future on an unknown entrenched battlefield . Inherits a lot of the neat stuff Interstation had like a completly different if not better combat system and a more complex/harder medical compared to TGcodebase servers. Visually it's inspired by the "Gone with a blastwave" e-comics but it has nothing to do with that universe. In short, WW1 trench warfare between red and blue in the grim darkness of the future. The server is mostly on during Mondays and Wednesdays and the playtests last around 2 to 3 hours, they have their own discord and shit.
/vg/station: 4chan's /vg/ server, based off an old version of Baystation and looks the most outdate compared to the servers but IMO retains the core and spirit of SS13 gameplay. Nigger word friendly, the admins are mostly cool but will ban your ass if you tip toe too much with shit like self-antaging and repeatly releasing the singularity as antag because that shit gets old fast. Has dedicated coders that iron out neat features from time to time, has the best cult gamemode compared to the TG one IMO. Allows different races but doesn't go into furfag territory: ERP is banneable and catbeast are valid to toolbox on sight. It's off the hub to keep newfags and furries away so you will have to go to the /vg/ thread or go to ss13.moe to get the IP.
Lesser or not lesser at all servers that deviate from the classic SS13 experience:
Colonial Marines and the other 2 or 3 offshoots: Played it a lot, but I would say it's a meh experience and it might get repetitive a lot. The main CM server may or may not have groomers as staff members. TDM Humans vs Xenos
Dead Space 13: Goes ON on the hub from every now and then, cool ideas but absolutely JANK codewise. Has coders like TheLion whose name is often tied to the SCP13 Drama shitfest, he might have changed since then. TDM Humans vs Necromorphs/Signals
Civ13: Neat ideas and the server staff is nigger word friendly, but it might come off as barren and it barely has players. Comes in Survival or TDM flavor.
Persistent Station: Played it once, has neat premise. Basically build a station from the ground up, people will try to expand the station as the round is basically never ending and server wipes after some months. Heard that the main host is a male feminist and I haven't played in a while. Still, cool concept.
Lifeweb: Hahaha, no. You will hear a lot of bad shit about this (mostly from reddit, but they are fags) but the server itself is pretty neat, unique lore, self-moderating community, no spoonfed allowed if not circlejerk-y at times. Forget it if you just got into the game, it will be hard to get in and the fact that it's a sekrit club you need an invite from the staff OR a high ranking player to get in the first place, plus a LOT of donations rewards that seem P2W to make you better in-game. All goes to feed the krokodil addiction of the russian dude who made it and hosts it. Pretty neat, overall.
Interpost - Hague (AKA Lifeweb clone): SS13, but with grimdark tint and Interstation combat and medical system. Mostly played by people that play, got banned from or aren't invited to the Lifeweb server. Nigger word friendly and for the most part pretty LRP.
Footnote: ERP is banneable in all of these servers, excluding Lifeweb and Interpost.
