I know what you mean. I'm a DC guy too, specifically Batman. Now I've suddenly got a Tony Stark (The Mechanic version) and Wolverine from
The Wolverine. I've also got the Mark XLII from
Iron Man 3 and Black Widow from
Captain America: The Winter Soldier pre-ordered. I'm contemplating a Thor, Iron Patriot, and will probably end up ordering a Captain America (most likely the stealth suit and Steve Rogers two pack). Damn this hobby.
I do feel like with Marvel characters though that most of them for me will be one and done purchases and I don't need multiple versions of the characters with exception to Iron Man as I'll likely end up with a couple armors and possibly Wolverine since I like the character. I also haven't really felt the urge to buy any of the Marvel villains thus far.
