It's the easiest to find any list of typical signs of a cult, and see how eerily they match. Let's pick
one by a dude who did a lot of research on cults:
The group is focused on a living leader to whom members seem to display excessively zealous, unquestioning commitment.
Yes.
The group is preoccupied with bringing in new members.
As far as trying to trick friends into trying SC.
The group is preoccupied with making money.
Pledge-based everything.
Questioning, doubt, and dissent are discouraged or even punished.
The very existence of this subreddit explains this.
Mind-numbing techniques (such as meditation, chanting, speaking in tongues, denunciation sessions, debilitating work routines) are used to suppress doubts about the group and its leader(s).
This one is a miss.
The leadership dictates sometimes in great detail how members should think, act, and feel (for example: members must get permission from leaders to date, change jobs, get married; leaders may prescribe what types of clothes to wear, where to live, how to discipline children, and so forth).
Not to extent of a full cult, but excessive control of feedback and even what is allowed to be written does fit here.
The group is elitist, claiming a special, exalted status for itself, its leader(s), and members (for example: the leader is considered the Messiah or an avatar; the group and/or the leader has a special mission to save humanity).
SC being the best game ever, backers being the true enlightened gamers, Chris being the saviour from publishers etc.
The group has a polarized us- versus-them mentality, which causes conflict with the wider society.
This needs no commentary
The group's leader is not accountable to any authorities (as are, for example, military commanders and ministers, priests, monks, and rabbis of mainstream denominations).
The group teaches or implies that its supposedly exalted ends justify means that members would have considered unethical before joining the group (for example: collecting money for bogus charities).
Chris is absolved of everything.Backers frequently excuse scummy marketing because it is to make SC dream real.
The leadership induces guilt feelings in members in order to control them.
Don't say negative feedback or you will hurt the devs and the game will be delayed.
Members' subservience to the group causes them to cut ties with family and friends, and to give up personal goals and activities that were of interest before joining the group.
Those stories of backers spending stuff saved for other goals just to get more ships ring a bell? Not sure if someone ever actually cut ties with friends over SC opinions.
Members are expected to devote inordinate amounts of time to the group.
Not quite, but some really do spend time evangelizing.
Members are encouraged or required to live and/or socialize only with other group members.
Not really, maybe metaphorically in terms of forums.
But read through these points, see how many are somehow covered by SC community, and now tell me that it is not an eerie thing to see.
