So... here they are all games in german : http://www.freankexpo.net/search.php...tool=-1&typ=-1

We have several visits from Germany, so you can add your games even if they are only in german (and vote and comment the other german games). No problem
Many users (also italian, french and spanish), even if don't know the dialogues, download (specially if they use rpg maker) the games to see the mapping, tips and triks, ecc.

I did games with rpg maker... and i played Versarbor only to see how it works.
