When I last played act III wasn't even out yet. It's been years. I too wonder if this is worth it. I didn't spent a TON of time on it but a fair amount back then and I've been on a "good porn game with actual game elements" kick lately, not just VNs.
Minotaurs
We've added a new Encounter to Emek's Rest. This one's based on the last Roundscape Poll you folks voted on. To trigger the content Meredith needs to be somewhat corrupted.
More Minotaaurs
This new Path comes with two new CG Scenes. One for both genders and one exclusive to Male PC.
Even more Minotaaaurs
This Path also features one new Castle NPC who'll get more content if you folks want to see more.
Clawyn Romance
Added a new CG Scene and final romantic encounter with Clawyn for Female Player Characters.
Mini-Bosses
We've added 8 new mini bosses all around Adorevia. All of them have a unique theme and will be a challenge to beat during Act 1.
New Lootz
We've added over 30 new unique Items to the game. Weapons, Armor, Rings and more.
All of them are rare, strong and sometimes have unique effects.
There is also a mention that once they release patch 6.0 it will be considered the "gold patch" that finishes the game.
"After the Release of Arenus we'll continue the work on the Gold Patch, version 6.0, for Roundscape Adorevia.
This Gold Patch will finish Roundscape, it will give closure to companions and stories who need it, a big focus on fixing bugs and polishing, finishing the gallery and quest journal but there'll also be a big surprise that no one will expect. "
Also for my own sake I made a text file where I added in all the changelogs since the walkthrough was last updated (I believe it was v5.0) so I would know what is in the game outside of the walkthrough.
It's just compilation of the changelogs v5.1-v5.8 in a note file but feel free to use it. I've removed the fix/bugs text since I felt those weren't needed.
The only one ik about is the meredith x mino one, you gotta beat emeks rest, then to the left of the main hall theres a new mino npc u can talk to. She needs to have 10 corruption tho.
