I've been away a while so I'm not sure if this web-comic gets any love here, but I'd like to highly recommend it to any boardgame/pen&paper RPG lovers.
Up To Four Players originally started as a basic panel comic dedicated to boardgaming culture humor. A quartet of board gaming Israeli-Brits love the hell out of board games, support their neighboring (literally) game store, and have occasional encounters with a possibly-thieving grandmotherly neighbor and a time-traveling delivery service.
A few years ago the strip switched gears and started focusing on role-played adventures, ala Table Titans, where the comic switches back and forth from the table to the adventure at hand. What I love about this is that the creators of the comic are also the creators of the campaign world they are playing in.
Crystal Heart for the Savage Worlds system. The setting is a world where humans are all born with stones for hearts that chisel and shape into the personality of that person over time. In the world there is an organization known as Syn that recruits people by removing their heart and adding a harness that can be loaded with a new heart: Crystals. The crystals are hunted by Syn and used to grant the users interchangeable powers. But with the powers often come personality quirks that players are encouraged to role-play, such as a stone-like crystal granting hardiness and stability, but also making the user seem to lack the ability to express any particular feelings beyond neutrality.
I especially like the Game Master choices that the character Nadav uses in the comics. He encourages all kinds of out-of-the-box thinking and never says no to the players. Whenever the players suggest something unique or even seem like they might be trying to find a loophole in the rules of the game, Nadav immediately tells them how much he loves the idea and lets rolls and or playing cards determine the results of their attempt.
The series also does a great job both entertaining and even teaching the Savage Worlds/Crystal Hearts system by bringing it up naturally as the story progresses.
I've never gotten the RPG myself but I've been considering it for some time. It's currently available in pdf as "pay-what-you-want" but at this point I feel like I should at least pay something.
When navigating the site, and you want to start with the very beginning comics, you'll have to select "Earlier Strips" under Chapters.
So if this one hasn't crossed your paths I highly recommend it. Currently only updating once-a-week but its typically the first comic I check for on Monday mornings.
