I only buy Volume 1s of each Marvel character/team, I like to read the origin stories etc.
But I'm not a big Avengers fan, I was always drawn more to the X-Men since I was a teenager.
So being an X-Men/Mutant addict I only buy those and the Subby volumes, which means I have to wait at least a year now for each volume
There's not even a Wolverine line yet!
