I feel old here but I remember back when I started in collecting, there were 3 X-titles. Uncanny. Then X-Factor came out to bring back the original team (It was like the classic Coke of X-men) and the up and comers New Mutants. It was easy to follow and once they had mutant crossovers or references, it wasn't all bad.
Same went with Avengers. Two titles. Avengers and West Coast plus the solo books of the main characters. Cap, Iron Man, Thor, etc...
Now there are way too many Avengers teams. And these lead characters have more than one book each as well like Cap and Bucky, Invincible Iron Man, Hulk, Incredible Hulks, etc... What blows my mind is when you get into a big event series. My last one was Fear Itself, it's crossover overload.
I will stick with following the Marvel heroes via cartoons and movies from now on.










X men and Batman killed comic book collecting for me. So many titles so much crossover and push for you to buy them all. They may not be the two that started it. But they seem to have the most crossover arcs.
Would it be so hard for them to publish one Xmen book weekly and have most of the mutants in one comic only. Soap operas have been doing it succefully (before facebook) for decades.
