Your Story and Our World look very impressive after a first quick scan. I like all the annotations and marginal notes, although I'd have preferred that the post-it notes had been marginal notes as well.
That makes my second gift copy of Sidekick, and three copies in total. I'm sure that means I'm destined to run a Sidekick campaign for the kids, when they're all old enough for Hero 5ER 2 math. And I am 3. :-)
That's Hero System, Fifth Edition, Revised.
Actually, the kids are probably readier for that than I am. I'm liking less and less math at the game table as I grow older and have less time to prepare and play.
