Last week I wrapped up Times Runs Out, which I thought was so-so (except for the awesomeness of the Thor-Hyperior team-up) and then Secret Wars, which quite frankly surprised me. I thought it was pretty damn good. I started reading it at the time in floppies, but stopped since I didn't know a lot of the back history leading into it. I really enjoyed it.
I did read the SW Old Man Logan mini when it came out, so I got a kick out of one of the lines when Strange tells Doom there's been a citing of a guy crossing the borders but we don't have much evidence. I liked the inside baseball to it. There is probably a lot more but other than OML and the Maestro mini that's all I read of the SW spin-offs that I recall.
