There is a lot of anime and spin-offs for gundam. Wow, I just realised that the Gundam I watched (Mobile Suit Gundam Wing) was also a spin-off from the original Gundam. I don't even think I watched the sequel for it.
Mobile suit gundam seed looks ok... *cough* Ishida Akira *cough* ... So, yeh, I will have to watch it one day.
Mobile suit gundam 00, the seiyuu casts seems really good. Hmmmm.
