Since January 2010, Westward has published a full color comic strip every weekday. Westward is a serial space adventure about mankind's first reckless steps into deep space in a starship torn by conflicting agendas and deep conspiracies. Complex and mind-bending, the story is inspired by classic sci-fi but delves into a tangled web of intrigue, revelations and existential horror. As Westward nears its 1,000th strip, a Kickstarter campaign has been launched to fund its further expansion: The production of not one, but two full color comic strips every weekday. The goal is to tell a parallel story, related to the main Westward storyline but distinct in tone and setting: A post-apocalyptic supernatural family drama. If a daily dose of original sci-fi adventure appeals to you, and a double dose appeals even more, check out westwardcomic.com and its October Kickstarter campaign, where you can watch a video explaining more about the project's history and goals. Westward is completely free, and its entire archive of nearly 1,000 strips is open for viewing.
I respect your judgement, Borgminister! I posted it in this forum because Westward is original sci-fi published for entertainment, not fan art of an existing franchise. It does make copious use of tropes, but always with a twist as the readers will attest.
I thought it was going to be one of Readyandwilling's threads. For a more comedic space opera that still deals with "big idea" science, check out Schlock Mercenary. It's a great webcomic that publishes 7 days a week. Been reading it for a couple years now.
