I first discovered 電波人間 on the Japanese Nintendo eShop. I watched a video and saw one of the DENPA men talking and thought, ‘This will be good listening practice!’
Actually, the game uses some kind of text to speech program and the audio is a little hard to understand, because it’s a computerized voice. So, it’s easier to just read the text than understand the quickly spoken and hard to understand voice of the main character, which is the only person in the game that has audio for his voice. (The new 電波人間のRPG FREE has audio for all of your Denpa ningen!)
I bought 電波人間 1 and 2 last year when 電波人間 3 had just came out in Japan, and they were promoting the series with a sale. Since then, 電波人間のRPG FREE has also come out.
What is 電波人間? 電波人間 are creatures that look like people that you can find anywhere there are radio waves. The literal translation is something like electric radio (wave) humans. Of course you need and 3DS and one of the 電波人間 games to see and catch them. Each of the games in the series has it’s own storyline. But in each game you have to assemble a team of 電波人間, which have different attributes depending on their color, equipped clothing, and antenna or lack of an antenna. Sometimes in the games, you solve other people’s problems and each game has various dungeons that you can explore, fight your way through and discover treasure.
Recently, I have been playing the free 電波人間 game. It has a lot of updates and you can decorate the island and houses your characters live in. There’s also a lot of event dungeons, sales and event 電波人間 that you can get.
