I'll continue to push for this. Destiny of an Emperor is marked as a port of Tenchi wo Kurau which is not recognizable to English audiences. Destiny of an Emperor is in English, and it has some bug fixes, which do alter strategies. It is frustrating for people who are interested in some of these niche games to not be able to find them because they don't know the Japanese names.

まぁどちらにしても表示される情報は IGDB 上に存在するものなので, 表示される情報が混雑を極めないことを願います。正しい情報をストリーマーが調べずに盲信することは怠惰だと思っているし, 移植されたタイトルがより良い方法で確認できることが望ましいと考えます。

Either way, the information to be displayed exists in the IGDB, so I hope that the displayed information is not too crowded. I think it's lazy for streamers to blindly trust the wrong information without looking it up, and I would prefer to see ported titles in a better way.

While I agree that duplicates can occur, that is a separate issue. This can happen with the original Sonic games where the 8-bit version of Sonic are ports of the Mega Drive/Genesis Sonic games as noted in this Twitch UserVoice: https://twitch.uservoice.com/forums/310210-discover/suggestions/45085204-twitch-category-name-collision

I believe this particular issue warrants some changes that Twitch must make should ported games be included in the category list. I do not think Twitch streamers want to go to IGDB to find the correct game title to stream and I do not see an issue with the way ported games are setup on IGDB.

基本的にはあなたの意見に賛成ですが, 翻訳により重複を含む可能性があるので, カテゴリ検索フィールドでの混乱を起こす可能性があります。
IGDBのデータベースでは重複を許さないため, もし移植作品タイトルが別の作品のオリジナルタイトルと同一のものだった場合, 衝突を起こす可能性が考えられます。これは当然技術的な問題なので, IGDB が工夫をすれば解決できるものだと思われますが, 検索したところ複数の同じタイトルが表示される状況が容易に想像できます。
あなたがカジュアルなストリーマーではなく熱心なゲーマーであるなら, （面倒ですが）IGDB で登録タイトルの詳細を調べることがより確実な方法だと思います。

Basically, I agree with you, but the translation can contain duplicates, which can cause confusion in the category search field.
Because the IGDB database does not allow duplicates, there is a possibility of conflict if the title of the ported work is the same as the original title of the other work. This is obviously a technical problem that IGDB could solve with some ingenuity, but it's easy to imagine a situation where a search would show multiple identical titles.
If you're an avid gamer rather than a casual streamer, I think (but annoyingly) finding out more about the titles on IGDB is the surer way.

I agree that games considers as ports should be included in the category list. My example is the game "River City Ransom", which is a well-known North American title. It is a considered a port of "Downtown Nekketsu Story", which is the Japanese title that is not as familiar to most audiences.
