The worth of Star Wars Dark Horse comics really fluctuates. Sometimes, a particular comic might be highly prized by collectors due to its rarity, art quality, or its role in the overall Star Wars story arc. But not all of them hold significant value.
The Dark Horse Star Wars comics are not canon. The Star Wars franchise has established a specific canon, and the works from Dark Horse aren't included. But they remain beloved by many for their unique takes on the universe.
It depends. Some Dark Horse Star Wars comics have been selectively incorporated into the canon, but many have not. The determination is made by the Lucasfilm Story Group based on various factors.
Dark Horse Comics is a significant player in the comic industry. They publish comics in different styles and themes, and have made a name for themselves with some really cool and unique offerings.
I wouldn't say Dark Horse Comics is bad. They have a diverse catalog with some really unique and interesting stories. But of course, not everything they put out will be a hit with every reader.
For the most part, they are canon. However, there might be some minor elements that are subject to interpretation or changes based on later developments in the franchise.
