It's interesting to me, but I never really got too into it. Back when sign was airing on Cartoon Network I used to watch it a lot, but I missed quite a few episodes and so I never fully understood everything. I watched the whole Twilight series of it, which was alright (although I heard the manga was much better) and I watched the beginning of Roots, but only like the first 9 episodes.
Never played any of the games though...

The anime of Legend of the Bracelet and the Manga have completely different storylines. The anime is generally not considered canonical because of that. It was enjoyable but it's not really a good representation of the series.
