Fun. Good Doom/Iron Man characterization. I always like when those two interact. You get the impression that Doom kinda enjoys kicking it with Iron Man versus battling Reed and the Fantastic Four. That one issue of Mighty Avengers when they're stuck in time with the Sentry was actually a lot of fun to read, 'cause of that.
Anyways, solid writing, decent art, nothing spectacular, but a good comic nonetheless.
Iron Man is decomissioning one of his old armors, but finds some memory recordings in there of an encounter with Doctor Doom he doesn't remember, then they show a flashback to it, where Doom tricks Iron Man into going to Mephisto's realm as part of a plot for Doom to get Excalibur - well any more and the spoilers would ruin it
