I used the F95 search and I read older posts, but I still don't understand what version is what because the way people are wording their answers is confusing. Legacy this. Actual that. None of that helps. So I'm going to write what I think the versions are in my own words, and hopefully someone can verify that it is correct or help me understand better. By the way, I am well aware that a lot of people think this guy is a scammer who doesn't release any real updates and has been milking money for years from around 450 supporters. I think that is scummy of him, but please help me understand the difference between the versions instead of just saying "don't bother to play."
So this is what I think the versions are...
VERSION: "Old Version".
This is the 0.98 CE version that was available over three years ago. The cheat mod works with it. Some people think that this version is better than the "Main Game" version, but then again some people think that the newer "Main Game" version is better. This "Old Version" is completely abandoned. It's just an archive of what the "Main Game" version once was a long time ago before some changes were made.
VERSION: "Main Game"
This is a remake of the "Old Version 0.98 CE" with some changes that some people didn't like and some additional content that most people feel was hardly anything worth adding. The "Main Game" version is currently 1.03.0 CE and it is possible that it might get tiny small updates in the future, but not very often. So if I check back in a year, it might be 1.04.1 CE or something like that. And I'm guessing that the Cheat Mod still works with this "Main Game" version because the Cheat Mod link isn't buried and hidden in the "Old Version" downloads section. The Cheat Mod did say that it will probably work with future versions, so maybe it still works with this 1.03.0 CE "Main Game" version.
VERSION: "Part II Aves"
This is Part 2 of "Old Version" / "Main Game". It doesn't have a Cheat Mod and it is what the developer is supposedly working on now (more so than the "Main Game" version). The "Old Version" and "Main Game" are essentially Part 1 with 10 acts. Part 2 will also have 10 acts but development is so slow it might take 5-10 years for that to happen, according to some people. And Part 3 is when there edit: might actually be sex between the mom and son, and right now it's still all teasers despite the fact that the game has been in development for 3-4 years?
--------
If what I wrote is correct, the developer needs to stop smoking crack and stop using stupid words like "legacy" and "Part X" and "airing" and "Aves". All he needs to do is get rid of the "old version" altogether and rename the other two versions to this:
Dual Family - Part I (write the version number like 1.03.0 CE and let people know if it is completed or ongoing)
Dual Family - Part II (write the version number so people will know if they have the most up-to-date version or not)
