Uhhh, no. A TRUE Kingdom Hearts fan doesn't get tired of playing the game over and over. I love this game as much as Kingdom Hearts, why? Because when I was 14 I bought Kingdom Hearts. I fell in love with it and like ( I'm hoping ) many others I felt a connection with the game, something I've never felt with a video game character in my life and I've been a gamer ever since I could pick up a control. Anyways, when I got Kingdom Hearts I beat the game 5 times, and still wasn't bored of it, I wanted to get every Trinity Mark, every dalmation and every treasure to get the secret ending. I was completely devoted to this game. As I grew up Kingdom Hearts was still a passion, but nothing like the original, KH:CoM and KH: Days almost made me lose faith in this amazing game. Then I played KH: BBS...I felt the same way I was when I first played Kingdom Hearts 8 years ago. Even though I've grown a long way from those days I'm still devoted to the series, specially to this game in particular. Long Live Kingdom Hearts : P
To answer your question, no, I'm not bored of KH: BBS.
