Well the long story is that the only "human" translation that is ok with the first page come from arzor and his team. But this translation is, at this point in time, only a merge for the translation of part 1-2 inside part 3. So no english translation of part 3. (but the first page is clearly lagging in terms of the version of the game)
If you want english translation you need to use machine translation with translater like mtool.
Early on mtool was the best source for translation because someone posted a file with a pre translated story for part 3 so you didn't have to use a lenghty process to play the game. I personally played part 3 from start to finish with mtool translation. The translation was pretty "meh" with a lot of gender error, interface error, name error. But it was playable.
Later we all got interested by the work of someone named bob serious who worked on some mtl translation and corrected the content manualy to have a more accurate and clean version of the game. His work comes from a discord where a bigger community is playing/talking about the game. I encourage you to go there if you want advices and answers (or to thx bob and the helper for their work).
Recently, Bob gave us the most up to date version of his work for part 3.04 that is the most recent version of the game.
This version is the most user friendly because mtool need a special process where the translation is loaded and the data of the entire game is loaded inside mtool every time you launch the game so every time you need to wait 3-4 mns on the starting screen waiting for this process before playing.
Bob mtl doesn't have this process and can launch in 10s by just clicking on the .exe file.
At the end of the day it's a choice between a "meh" translation with mtool but with the most powerfull cheat engine I have seen on the market that can edit the game in real time and give you access to a lot of data and cheat or a "cleaner" human translation that is more stable and friendly to use.
you can pick both of these version on my gofile if you want
You must be registered to see the links
the bob mtl is named : MGQ3.04 bob MTL version.rar
the mtool version is named : MGQParadox3.04 with mtool(+save+mod.).rar
(don't look at the version of the top left side of the starting screen, it's a visual bug, the version of these link are 3.04)
I encourage you to play with the bob translation for most of the content and only use mtool if you really want to cheat in order to multiply xp or add item in your inventory.
Since 3.02 the dev has given us an option to cheat the monster stat to make them so low that you can one shot most of the content of the game (with an item called rulers rules that you can access in your castle if you put the game in the easy difficulty), so cheating is becoming less important.
