Well, I've taken one more step in the long road to the comics industry in that I've made a webcomic. It's called "The Mighty Meteorite" and is pretty much a superhero title. The main character is partly based on my ComicVine character.
I think a good Avengers lineup would be with the "major" Avengers, per se. About 90% of major Marvel heroes have been Avengers (and most of the ones that haven't been Avengers have been on an X-Men related team), and the novelty of being an Avenger wears thin. They should make being an Avengers a privilege, for the characters that actually deserve Avengers membership, rather than just saying "Hey, there's a popular character, lets stick them in the Avengers so we get more sales".
What about..... JEAN GREY!! She's died twice! The first time I read Uncanny X-Men #137, I remember saying to myself, "Oh yeah, the X-Men will win. It's not like they'll kill off one of the main characters." How wrong I was.
And then there was the second time, when that douche Xorn showed what a douche he was.
The Age of Apocalypse would make for an awesome game. There could be two modes: Evil Mode and Good Mode. In Evil Mode you get to play as Apocalypse and can choose people to make your Horsemen. As the game proceeds you can play as the Horsemen as well. At the same time you have to try to take over the world and weed out the weak. In Good Mode you play as Magneto at the start, and it is set after Apocalypse has taken over the world. You have to recruit X-Men and overthrow Apocalypse.
