Really, Who else could it be? http://www.originsawards.net/2016-origins-award-winners/

Can't think of anyone else, really. I have a bunch of RPG systems under my belt but I can't think of any of 'em I liked better.

Makes perfect sense to me! Congratulations, indeed!

I play in a regular group that plays several RPG's (with have 2 Star Wars GMs, but also, Dark Heresy, Stargate & Laundry Files). One of the GMs has converted the dice mechanic to Deathwatch, and players that haven't played SW are commenting on how they like the dice system. It's definitely my favourite.

Good to see the wins for Armada & Imperial Assault too, they're all great games.
