We receive high double digit new players every single day on /tg/station's servers. Most don't make it past a week due to the high learning curve but we would not be sustainable without the consistent influx of fresh minds to be amazed by the depth of the game, as the biggest source of drop off for people who make it past the first week is people who've learned all the advanced mechanics and had their emergent gameplay moments ("wait, you can do that?").
Nope, but that's why you should play anyways :)
SS13 is, IMO, an inherently newbie-unfriendly game. However, there are servers and new players guides online, for Goon (one group of servers) and tg (another group of servers), and probably others that I'm not familiar with.
