Which translation is better for you ?

[Pianica]

fan-made patch or SEA version ? (I'm a JP player in ship2)

*This is sample case. If you know any other case, (e.g. class, weapon, character name etc.....)Please tell me and Let's talk about this. (I study about fan translation. )

(fan-made patch)　Subdue Za Oodan
Naberius' formerly peaceful Oodan popuration has suddenly become violent, particularly the Za Oodan.
Protect the ecosystem by suppressing the berserk Za Oodan!

(SEA version) Zawoodan Subdual
Reports have come in that native species on the planet Naberius have turned violent.
The commonly-seen Woodan creatures, especially the Zawoodan subspecies, have become particularly aggressive.
Defeat the Zawoodans to preserve the ecosystem.

（日本語）ザウーダン討伐
惑星ナベリウスに居住する原生種の凶暴性が増しているとの報告があった。
原生種として多く見かけるウーダン特に、その亜種であるザウーダンの凶暴化が顕著である。
生態系を維持するため、凶暴化したザウーダンの撃退を依頼する。

I prefer fan translation a lot more. SEA has a few decent translations but horribly butcher others.

I think there needs to be some distinguishing. Everyone hates the SEA translations because of the names it uses for terminology, but the translation itself (tooltips, chatter text, etc) seems extremely top-notch with hardly any faults.

I haven't really looked into it much though, don't care.

For the instance you give, SEA is more correct.
The fan translation is more of a summary, while the SEA one is a lot more accurate.

[Sizustar]

Tunnel = Underwork
Caluldren = Volcano

[Rien]

Technic = magic
and Force = wizard

are the ones that put me off the most.

From that text, I prefer the SEA, and having played both servers, there are some good and bad things from both. For example, in story mode, fan translations will sometimes be more accurate, while official translation will be more literate and properly localized (in all the meanings), but I've also encountered some "lost in translation" in SEA (hearing the japanese audio makes it very obvious). The patch has a lot of mistakes, and we should all collaborate on fixing them, but sometimes you take a screenshot and then realize you had it configured to make clean shots without texts also, not everyone is native English speaker to know for sure what's the best correction.

Oooh, that's where the crappy units potential menu translation is coming from.
