One of the things I like about it is, unlike many other superhero games, I can actually generate a character in about 5-10 minutes or so.
The mechanic is really straightforward - roll ‘D616’ (3D6 with a Marvel Die included, which replaces the ‘1’ with a crit result instead) and beat a target number which is essentially a Characteristic score +10. The Characteristic scores are a bit abstracted, but can be read in the same manner as the bonus-score scale from D&D (where 1 is the same as a +1 bonus, 2 is a +2 bonus etc). It doesn’t work quite the same as the D20 system as the D616 is a bell curve result rather than linear, but it is familiar still. The Powers section may take a bit of a learning curve, but no more than D&D-style feats or the like and, thankfully, they haven’t overburdened the system with a massive skill list. Reading a Marvel die as a multiplier for the damage bonus also makes combat really easy to calculate too.
If this is coupled with some good, full colour production standards and taps into the full range of source material (which is a lot of comics/movies) then I can see it as being very worth it for me. I’ve found most supers games to have problems of one sort or another and, unlike D&D, Traveller and Call of Cthulhu which each fulfil my basic wants for fantasy, sci-fi and horror gaming respectively, I’ve never really found a game that satisfies for the Supers genre. Till now, maybe.
