Maybe this would fit better in the discussion board o:))
This is going to be super scatterbrained as I throw my thoughts here-
I definitely find myself being attracted to one-word names, especially those that are in another language or simply made up. I don't think I'm able to pinpoint why, it's just more aesthetically pleasing imo. Maybe it seems more professional? More unique? Adding "pack", "clan", "pride" might actually turn me away from the group, simply because, in my opinion, it doesn't suggest any sort of individuality or uniquity. I also enjoy "storybook" style names. Some older examples I've seen are Day of Wrath or Reach of the River. If a tag at the end of the name is used, having something that's actually pronounceable rather than a jumble of letters pulls me in as well, especially if it isn't a direct abbreviation created from pulling the first letters in the name!
I don't actually join many roleplay groups and then make a new character-- I like to find groups that suit a character I already have instead (unless the roleplay seems super fascinating and I see the opportunity to make an interesting character I would enjoy playing). Because of that, the amount of members doesn't usually have a huge impact on my decision to join. However I definitely prefer roleplays that include some sort of malevolence in the plot, it just makes everything more interesting!
Anyway that was my splurge. I myself am pretty picky..
