Civil War: X-Men

Or should it be X-Men: Civil War? Anyway, I'm trying to catch up to the last decade by reading various Marvel collections about big events such as this, which goes through some of the mutant titles and explains their involvement in the superhero war over registering heroes. I only really got into the Wolverine issues, which surprised me since I'm the only person on the planet that doesn't really care about him. And yet I think that arc worked because it focused on one hero with one main purpose. Otherwise, there is a lot of talk by characters I don't know and referencing events I also don't know. What happened to that trying to figure out what has happened bit?
