T8 is the 100$ tier and they can design a character for the game, the problem is when the Patreon stops supporting or goes to a lover tier the character will no longer be in the game, at least that is what is known because Bluecat hasn't said anything about them.
This is the current T8 list from Patreon.
I got it, thanks for the explanation. It has been awhile, of course, but I remember about half of these characters. Some I like better than others, but I had no idea they were not considered permanent. I am more amazed that Bluecat found enough people to donate $100 a month for years to support so many T8 characters.
To add a character for several updates, and then remove her once the donor reduces their donation is a pretty poor experience for the players. I don't know if this is Bluecat's intention, but that has no other result than to annoy many of his fans.
The issue with the T8 characters is they dilute the game too much. I've said this previously, a long time ago, but this game has way too many LI's. You can't keep track of who all these people are, why they exist and most of their scenes are filler or randomly placed in a way that the story doesn't make sense . Personally, I can't remember any of them besides the family members and a few of the other main LI's.
I completely agree with this. I know Bluecat wants ES to have more characters than any other VN, but eventually they all sort of blend together. I can only remember the names of about 10 or so side characters, without having to look at the guide, and many, many, times a character shows up that seems to know Sensei previously and I keep thinking to myself, "Who is this again? Where did I see her before?"
Your comment about random scenes, is also spot on. There are countless sequences where Sensei has an interaction with some character, say in the school hallway, or walking around the town, that doesn't have anything to do with the story, and is quickly forgettable. I wish he would focus on a few key plot threads, and a handful of side characters that the player can actually keep track of, and just keep developing that. For example, I would like to see more about what he plans to do with the night club. I think there is a lot of potential for interesting plot development there, but it of course has to compete with many other story arcs and random scenes.
