Well, matarika said pretty much everything so what i'll say is very secondary.

We can say i abandoned TB more than a year ago, and i think making the game great would make me come back to the game, but now i'll tell my suggestion.

I learned one thing playing MapleStory 2, maple is a diying game, but in SA server there's a dude that makes some cool stream, normally interviewing a well known player in community, and for me that's something really useful to maintain the people who still play the game, so that's a suggestion more for the future, but we can use now, as a test, how many players will watch? Sending globals will certainly help, maybe making a weekly podcast? inviting important players, or players with a high rank, idk, i think it's a really good way to entertain the player.

maybe making the entertainment squad for it, well, event squad is an entertainment squad too if u think like that, but make a squad more focused in the media, just like videos and post for social media as matarika mentioned.
