There is! I actually discovered the system through an actual play called Legends of Tabletop. The first one they did was actually with the creator and it uses a version called Daytrippers. Since then they've done a handful of CORE games, like a Cthulhu version, some sci-fi, and classic fantasy.

This was probably one of my favorite systems when it comes to just a giant list of potential skills. The way they're grouped by level and just the crunch of leveling was fun.
So my favorite system right now is CORE. The resolution mechanic breaks down into a combination of Yes/No and And/But. So for instance you can get an okay result that is "Yes, But" where you succeed but at a cost. You could also fail spectacularly with a "No, And" where not only do your not succeed but something even worse happens. The only thing there isn't a result for is just a straight up "No" because that doesn't help move the story along.
Shield Maidens looks awesome!
My group is kind of all over the place. We currently play Deadlands, Star Wars Saga, Cthulhu Invictus, and COREthulhu. Plus we're also playtesting a work-in-progress system.
I've used it for random generation and that's about it. Before each session I'll generate a list of random people and stores. I've also used it to come up with lists of random items.
It's basically just an all-in-one random generator for me.
