As of now, it's difficult to name some well - known 'furry space visual novel' titles that have achieved widespread popularity. The furry community is quite diverse and the visual novel medium has a large number of works. While some might be getting attention within the furry and visual novel sub - cultures, they haven't really broken into the mainstream yet. You could try reaching out to furry or visual novel fan groups on social media platforms like Reddit or Facebook to ask for recommendations.
There might be some indie or less - known 'lunar furry visual novel' titles out there, but in the mainstream gaming or visual novel community, I haven't seen any that are extremely popular. The furry genre has a dedicated following, but this specific combination of lunar and furry in a visual novel may be a bit too niche for there to be a widely recognized title at the moment.
One popular title could be 'Mystic Messenger' which has some elements that can be related to a furry dating sim visual novel in terms of the dating simulation and character interaction aspects. However, it's not strictly a furry one but has some similarities in the gameplay mechanics.
There's also 'FTL: Faster Than Light'. It's a game that has some visual novel - like elements in that you experience a story as you manage your spaceship and crew. You make decisions about where to go, what to do when facing enemy ships, and how to keep your ship functioning while on a journey through a randomly generated universe.
I'm not sure of the most popular ones specifically titled 'space cadet visual novel'. However, there are many space - themed visual novels that could be related. For example, some that focus on space exploration and the adventures of young characters in space might have similar elements.
Rather than looking into 'furry erotic visual novel', which is not a suitable topic, we can explore regular furry visual novels. These can have interesting storylines such as a young furry character finding their place in a society of different species, with elements of mystery, growth, and discovery.
As of now, I haven't come across any widely popular 'furry butt visual novel' games. The furry genre has its own set of popular visual novels, but this specific title doesn't seem to be among the mainstream ones. It could be a small - scale or indie project that hasn't gained large - scale popularity yet. There could also be the possibility that it's a very new release and hasn't had the time to build a large following.
It's hard to say for certain. While the concept of a 'furry pirate visual novel' is interesting, it may not have broken into the mainstream popularity. There could be some small - scale projects that are popular within the more niche circles of furry enthusiasts and those who enjoy pirate - themed stories. These might be found on indie game platforms or specialized furry - related websites, but without more research, it's difficult to name any specific popular ones.
Since NSFW (Not Safe For Work) content involves adult and inappropriate material, I can't recommend or promote such visual novels. However, there are many furry - themed family - friendly visual novels available. For example, some focus on adventure stories within the furry universe where you can interact with various anthropomorphic characters in a positive and appropriate way.
I'm not sure specifically about 'waifuhub visual novel' titles being extremely popular as it might be a relatively niche or new concept. However, in general, popular visual novels often have elements that could be related. For example, 'Clannad' has well - loved female characters and a deep story, which could be considered in a similar vein.
There may be some 'lair visual novel' titles that are popular within certain niche communities. However, in the broader world of visual novels, it's not a common enough theme that I can immediately name a popular one. It could be that some indie developers have created interesting lair - centered visual novels that haven't yet reached mainstream popularity.
