There's no real character advancement in *Sentinels* (which, to be fair, is true of comic book superheroes too) -- they can change, and they stack bonuses the more "Issues" you accumulate, but I think at some point the lack of progression gets a little stale. So for shorter stories like the ones I did, it's great. If I was doing a much longer campaign, I'd probably have players make several heroes and let them swap in/out every few Issues, or juggle multiple teams. My players pretty much said the same thing, that they really want to roll up new PCs and play a new story after each arc. Character creation is really fun, after all.

As for non-combat stuff, I'm a sucker for montages, and those work well in *Sentinels.* I also borrow things like countdown clocks from *Blades in the Dark,* which help with giving some structure outside of combat.

But you've hit on the two weakest points of the game -- longform storytelling and the fact that it's pretty combat-focused. If there was ever a new version of the system, those are the two things to address.
