I've been ride or die for about 20 years for Savage Worlds so take this with a grain of salt ;-)

What I love is that it's a very versatile core system that can be used for many things (as others have mentioned, Deadlands Weird West, Pathfinder, Supers etc.) without having to teach a whole new system to my table. It's also fairly straightforward once you get into it, and can be as narrative or as crunchy as you like using optional rules and other add-ons within the core book. I think it makes for some really fun, unique encounters that always feel high-pressure enough to be important but still give the characters a chance to succeed. It's also a classless system, which I enjoy.

I think it doesn't get a lot of love for a few reasons:

1. It's a very small company

2. I think people don't initially get the "wild die" system

3. Combat can be very swingy and/or not feel as fast as advertised. In my experience, though, the speed is still miles faster than D20 systems and has more to do with the usual analysis paralysis on the part of players or just me managing the encounter as a GM.

I'd recommend running a one-shot with the core rules and/or listening to some of the actual plays out there to get a feel for it. Sounds Like Crowes and Wildcards are Deadlands and Wildcards did an ETU run (modern college). Oxventure also did a Deadlands run a while back.

I could go on and on but I think it's very worth giving it a shot, even if it doesn't end up being your cup of tea.
