My friend showed me this game yesterday. He plays it on a nintendo ds emulator on his computer and is addicted to it. He gave me the game but I'm not playing it. I don't know how he gets by as the whole game is in japanese. But he's learning japanese so he's not necessarily fully handicapped. Actually that game came out in September, 2009 and is revolutionary in the anime world. Otakus who can't get girlfriends are quite delighted by this game. Yes, that guy married a character called Nene on that game. I knew about this last month. There is also a case where someone divorced his wife because of that game too.
Hackers are also cracking the game to make an english version.
