Well, there is no Programming in Japanese or Turkish; it’s in Java, C++, C# etc and all of them are English. In Turkey most CS people work on IT and it’s pretty advanced actually, but I’m more interested in studying on 3D Graphics Engines and that sector is almost non-existent here. Sure I can try my chance in Europe or US but Japan is more interesting. Besides who doesn’t need to learn another language. (Yeah I’m learning a foreign language using another foreign language, so cool!)
There are many Japanese RPG games, but recently I played Dark Souls and it’s very good game. There are also visual novels that are partially rpg games that you can check them out here (“vndb.org” like imdb for visual novels). If you like reading they are great, but they can be a bit kinky sometimes so I advise you to check their age ratings first.
