Suikoden Tierkreis is easily my favorite DS game. I enjoy the plot, the characters, the world, the fighting, the quests, the graphics, the music and EVEN the craptastic English dubbing (I fell for Conon, one of the villains - his dub VA is incredibly good compared to the rest. Asad is awesome, too.). ...I bought the game some time ago and I also downloaded a Japanese rom with English subs (I don't think it's illegal if you already have the game?).
Frankly put, most of the Japanese voices are fantastic compared to the dub. But for some reason, they managed to find a few dubbers who are better than the original ones! O_o;
...Like Dirk. The Japanese one is very lackluster (...the voice actor is really good and prolific and one of my favorites so it was a shock for me) and the English one sucks in dialogue scenes... but when he turned evil, laughed like a maniac and jumped out a window, the English one drew the longer end of the stick. He NAILED that scene. ...I know Katsuyuki Konishi can do a better evil laugh than he did, though... I'll never understand what went wrong with his performance in this game. :\
