請問要怎麼把遊戲內日文改成中文~

Enough stupid crap on Steam in English.

This game is just too old to run on windows 10, that it can not run with more than 10 FPS, totally unplayable.

why isnt this a requirement for steam

Let's run through the benefits: #1: More people will be able to appreciate this game. #2: Koei Tecmo will get more fans. #3: Koei Tecmo will make much, much, much, much, much, much, much, much, much, much, much, much more money.
