Speaking of Yu-Gi-Oh!, I started playing Nightmare Troubadour on my bro's NDS. I noticed that he had a Japanese ROM, probably by mistake since he also has an English one loaded too. In case you're wondering, these are all on a Top Toy flash card. My Japanese is still good enough that I can understand the gist of the lines but my kanji vocabulary is lacking. Playing this game is only sort of helpful for practice though. I think a visual novel would be more intensive on dialogue, hmm?
