hello in sorrow we trust,
this topic is something i think a bit interesting to approach. from my personal experience on the server i feel more included, the less 'directly' included i find myself. my personal paths have had me in factions that use discord, and, factions that use strict in game communication methods. this goes between settlement work, private faction things, and even taverns on the persistent world, arelith.
i will answer your questions in order, to build my thoughts out.
What does inclusiveness look like to you?
this looks like roleplay. interactions can be 'bad' or 'good' for my character, but it ensures i have roleplay. this can be seen as:
joining groups, and having players/characters who are interested in the story web you are spinning
active in settlements, and becoming one of the characters that people know they can approach for certain roleplay moments or activities
activity in specific fields of focus: this one is broad by Design because it can be 'playing a merchant' or 'being a sailor' or 'good at X activity'
following anything similar to that, assures someone can be included in more roleplay avenues. inclusiveness to me is activity, story generation, and giving players your time, to receive back interesting moments and roleplay in equal turn.
i enjoyed xerah's comments also on:
Coming over to talk to you for no reason other than they don't know you.
What does it mean?
if i understand this question, it reads like 'what does it[inclusiveness] mean?'
being inclusive is ensuring characters designed for specific niche roleplay moments, are offered their share of moments.
it means that people who run factions, will include
it works through in character interactions, held on the server, that improve the quality of a character's life through giving the player behind the character, more reasons to log in and want to stick around
What are some things other people have done to make you feel included, or inclined to be interested in their story?
i enjoy when people have consistent enough schedules of play through a life cycle of one of my characters, and they will send me wisps, or hins, or goblins for the sake of creating or furthering roleplay between characters. when you can see a character or members of a faction more, it is easier to feel more included.
What are some grave sins that turned you away from feeling included by someone in the past?
my personal sorrows with being inclusive is when OOC communication (discord, sending irl letters, skype, smoke signals) is used to coerce a character into existence that otherwise would not be around. i have always started to feel worse, or uninspired, in situations where community becomes OOC communications rather than someone having the time and desire to play on the persistent world, arelith.
becoming 'too inclusive' to where arelith feels more like an MMO (massively multiplayer online game) instead of a NWN persistent world, often feels like a detriment rather than a path toward better story telling.
its a lot to say that i think being inclusive starts with being characters, activity in hub sections of Arelith, and giving characters means/ability to approach you to generate more sections to the web of story. when things become too OOC, or when people aren't willing to return attention via smaller-roleplay moments, i feel Excluded rather than Included.
