I only just got around to ordering 26 there now.
As I've said before, but I feel like saying again, I've always loved Excel Saga, but the massive delay between volumes definitely killed it a bit for me.
I remember I bought the first volumes from Forbidden Planet probably about 6 years ago? Back when I was around 17, and reading them volume after volume over a couple of years, along with Hellsing, the only other manga I've actually bought.
And loving it big time, I just found the humour so amusing, I liked the art and the story was wacky and enjoyable. My interest peaked massively in the volume Dr Kabapu revealed that he and Il Palazzo were 20,000 years old and all of a sudden there was an actual legitimate storyline.
However it was unfortunately soon after this point that the Volumes started being released so slowly, it was fine for the first one or two but after that the distance between them was just too long for me.
I still intend to finish the series because I maintain interest in it, but I never finished volume 24 when it came out and have had 25 sitting beside my bed unread since I got it because I've a full time job now etc, and just finding the motivation to pick up a mangabook and read it is difficult.
I read other manga online still, but I've found it difficult to actually pick up the last couple of books even though I'm still massively fond of the series.
