Ahh, good old DGM. I've been following it since it started. It's great and all but why did it have to become monthly *^* At least it's not on hiatus. Lol. My friend introduced me to Nura, I ended up marathon reading it to catch up. It's awesome.
My old favourites would have to be KHR, Bleach (kinda getting tired of it), KWMS, Koko ni Iru yo and Haigakura. Though Haigakura took me a while to figure out.
It's been a long time. I have fond memories of Cardcaptor Sakura and Full Moon wo Sagashite. Also Kare Kano and Hana-Kimi.
Ranma 1/2 and Rurouni Kenshin hold a special place in my heart, too.
But I don't think I'll ever get rid of the first few volumes of Naruto. My first purchased volume back in the day when it first came out, and the story just sucks you in, no matter how long it's been since you've last read it.
