People that are better than me at this! Thanks guys, for inspiring me to do this!
Steven and The Crystal GMs by Rastaba
Inspired by the likes of Darths & Droids, One Piece 3.5, and many more which have come before it, it is a campaign webcomic. This one following the adventures of a group of players in a homebrew campaign following the story of young Steven and the millenia old crystal gems who protect the world from monsters...who are a group of players sitting around a table throwing dice at each other.

Naruto: Jutsu and Jinchuriki by RandomRex6
Do you like Naruto? Do you like tabletop gaming? Well watched them be united by someone whose never played one and has no comic experience! It's better than it sounds, I promise.
D&D Aangvanced by DeadpanSal
Long ago, the players rolled in harmony. Then everything changed when the new DM started a homebrewed campaign.
Guildhalls and Dragonslayers by Simvig
This is a campaign comic based on Fairy Tail in the style of the original DM of the Rings and Darths and Droids. This means that in the comic world the Fairy Tail anime and manga do not exist, instead the GM is trying to run the story as a roleplaying campaign.
One Piece: Grand Line 3.5 by DragonTrainer
So... yeah. Some time ago, I went on an archive binge on Darths & Droids. If you know what I'm talkin about, then you probably know what's coming up. I decided to give it a shot and here's what I came up with: One Piece if it were a roleplaying campaign. :p
Darths and Droids by Irregular Webcomic
Darths & Droids is an "RPG screencap comic. It's one of the older ones, and is still good to this day.
And the original....... Drum Roll Please, dadaddadadaadadaddadada...
GM of The Rings by Seamus Young
Lord of the Rings is more or less the foundation of modern D&D. The latter rose from the former, although the two are now so estranged that to reunite them would be an act of savage madness. Imagine a gaggle of modern hack-n-slash roleplayers who had somehow never been exposed to the original Tolkien mythos, and then imagine taking those players and trying to introduce them to Tolkien via a D&D campaign.
