MarkoH01: Afaik they lost at least one person who did the VO and had to search for a new one so it is a lot of work to do and it could really take long until the VO will finally get completed.
Yep, but that affects all versions and is not topic for the "second class citizens". I can wait for voice over, no problem. But what's in versions on other platforms should be here as well.
MarkoH01: Regarding the "new feature" on Lust Theory 1 it feels more as if they are creating (once again) another game based on the Unreal Engine with the Lust Theory 1 story ... at least it feels this way to me.
They are working on a Unreal Lust Theory game, but that has nothing to do with Season 1.
I haven't really tried to find out what the new feature is, but I think I saw it was the same voiced narration like in the beach day event in season 2, for which they apparently used a AI (I can confirm that it's not the standard Ren'Py voice, since that - in my case - reads as if the games were written in german).
