Superhero Gaming is definitely considered a level behind your standard fantasy in terms of gaming done and titles available. I personally think they continually jostle with sci-fi, pulp, and horror for the 2-3-4-5 spots in the hobby. But that doesn’t mean there hasn’t been an explosion of superhero games in recent years.
Of course, Green Ronin has Mutants & Masterminds and the DC Comics license waiting in the wings. Besides these, you have the hot new ICONS RPG by Adamant Entertainment. Add to this the ENnie-nominated BASH! Ultimate Edition, Margaret Weis Productions and Smallville, and Superhero RPGs seem to be getting a lot of attention just now!
Aside from all this, there’s still Heroes Unlimited floating around, adherents of Marvel Superheroes, its derivative 4C System, and small-press efforts like Capes, Resolute, Hearts & Souls, and one of my favorites, Truth & Justice. Plus, let’s not forget Hero Games and Champions!
Oh, but we’re not done. Superworld, Mayfair’s old DC Heroes game, Squadron U.K., Brave New World, Silver Age Sentinels, Aberrant, Godlike, and Wild Talents are out there, too, in one capacity or another.
Add in the recent re-release of the classic Villains & Vigilantes (tearing up the charts at RPGNow, don't you know?), and superhero games just might be enjoying a—dare I say it?— small renaissance of sorts.
(Now, a harder question--which ones stand above the fray? I like the old Marvel FASERIP system, Truth & Justice, and I'm really liking ICONS. All are lighter on rules, I suppose. But there's no shortage of games to try in this category).
