What are the best character developments in this game? I find this particular topic interesting since I have seen quite a few changes that seem incredible to me.
Depends on what you mean by character development. Even though all of the characters are still WIP, the Bareshade/Lizard Tribe ones have the most scenes so far and are the most developed (Logan and Roushk are my favourites here). Bernard probably is the most complete character with the most complete romance.
Logan and Korg are my favourite characters in general. Scar and Tank, who I also like, have been developed quite well as the story goes along, Tank ends up being surprisingly compelling. I also have to mention Rose, a rather fun and interesting character, imo, who becomes more and more prominent as the story goes along (also one of the very few major female characters, which you might or might not be into, though either way there is no erotic content featuring her right now).
Some people seem to really like Gunnar. He probably has the most erotic scenes in the game and, allegedly, some good romantic scenes
as long as you enjoy sub/bottom content. None of that really appeals to me, so he ends up being just kind of annoying and way too stubborn.
How many years of development do you think the game needs to be finished according to you and why?
Can't even begin to estimate. The main story will probably take another few years, but the side content/areas could extend that even more.
And the final question would be if someone can explain to me a small drama that this game has, specifically about the design/art change that occurred in the game, as I told you, I am playing again after a long time and I really don't understand those problems.
The main artist had stopped working on the game around two years ago, and so a new artist had to take on that role while the other was taking a break/leaving indefinitely (other supporting artists have also come onboard since then). No one really knows exactly why they decided to take a break from/leave the project, so there has been some speculation that something happened behind the scenes. Either way, some people really didn't like the new art and were quite vocal about it. This eventually led to Hyao, the main dev, making a post talking about how the negativity surrounding the new updates and development was realy affecting the team's motivation and enthusiasm for the project.
This was all quite a while ago now, and the team seems to have recovered since then, but there might have been some lasting consequences (it might be completely unrelated, but most of the guest writers seem to have stopped writing for the project since then, and the guest character introduced around that time, Garuik, hasn't really got any new scenes or content after that).
And as an extra, which characters they think will have a good development in the future or what plots they would like to see developed.
In no particular order, I want to see the Mythshore story continue and new content for the associated characters, more development for the Western Island and Eastern half of the continent, and more content and development for the Orcs (relationship building, romance, erotic scenes).
