With my examples of play, such as the M. Bison vs. Magneto one here. And a couple others I have on my forum at Myth-Weavers, like the prequel to the above example, Maximum Wesker.
It feels good! Plus, my own MHR games are going well, such as Earth's Mightiest Rookies over on RPOL. Writing for the system is fun and writing up things to help people see how a narrative and the rules behind it match up is good exercise for me. I think one of these days, I'm going to have to ask MWP if they need more writers. I love Marvel comics and this game has been tremendously fun to play and use it to create.
Lately, I am thinking about gaming with MHR in the Marvel Movieverse.
