Reddit reviews Commencement (Star Wars: Knights of the Old Republic, Vol. 1)

Warning! Long-as-shit recommendation post incoming!

Halo:

There are several ones published by Marvel, haven't read any but my friend, whose a big Halo fan liked Halo: Blood line by Fred Van Lente

Mass Effect:

These are all written by Mac Walters, the lead writer of Mass Effect 3

• Mass effect: Redemption Liara tries to find Shepard body, set between the intro of ME2 and when Shepard wakes up in the Cerberus Lab.
  
  
• Mass Effect: Evolution The origins of the Illusive Man, set during the first contact war.
  
  
• Mass Effect: Invasion Aria defends Omega against husks and Cerberus, explains why she's on the citadel and sets the Stage for the Omega DLC
  
  
• Mass Effect: Blasto: Eternity is Forever The most glorious of all comic books.
  
  Star Wars:
  
  
• Star Wars by Brian Wood and Carlos D'Anda, set directly after Ep IV, the first TPB isn't out yet, go pick it up in floppies.
  
  
• Star Wars: Tales of the Jedi set waay back in the time-line, before Star Wars: KOTOR and Old Republic, focuses on the discovery of the Sith species among other things.
  
  
• Star Wars: Dark Empire and Empire's end set after the movies, features the return of a character, Don't want to spoil who it is. Sets the stage for Crimson Empire.
  
  
• Star Wars: Crimson Empire I,II,III (there's a collected version with all three), Follows the last Imperial Guardsman(the dudes in red armor) on his quest to bring the traitors of the Empire to justice
  
  
• Star Wars Legacy I, Star Wars: Legacy II just got started and it's been really good so far. Set 130 years after the movies, I follows Cade Skywalker and him coming to terms with his legacy. II follows Ania Solo, who's not force-sensitive, who has to deal with finding a lightsaber and being hunted by Imperial Knights(Imperial Jedi).
  
  
• Star Wars Knights of the Old Republic, set before the video game, follows Zayne Carrick after he's been accused of murdering his fellow Padawans. No worth reading after the main plot ends.
  
  
• Star Wars: Dawn of the Jedi, starts with the founding of the Jeda'ii order and first contact with the Rakata's Infinite Empire and their Force Hounds, The Next arc will be the Force Wars(the first schism between the light and the Dark side)
  
  They have 25$ omnibii for most of the series they've made, except for the new Legacy, Star Wars by Brian Wood and Dawn of the Jedi.
  
  
  Lighthearted books:
  
  
• Adventure Time by Ryan North with art by Shelli Paroline and Braden Lamb.
  
  
• Plants vs. Zombies: Lawnmageddon by Paul Tobin and Ron Chan a digital series on Dark Horse Digital, will be collected into a Hardcover eventually.
  
  
  Sci-Fi:
  
  
• Saga by Brian K. Vaughn and Fiona Staples, two lover are hunted across the galaxy by bounty hunters and military police. It's also weeeeeeiiiiird and at times disgusting.
  
  There are also several Firefly/Serenity comics if that your thing, they are all good.
  
  
  
• Spiderman
  
  The best place to start is the current Superior Spider-man, Which stars a slightly different Peter Parker
  
  
  
• Batman:
  
  
• Batman By Scott Snyder and Greg Capullo, it's batman bringing justice to the superstitious and cowardly lot that is criminals, there really isn't more to it.
  
  
• Batman Beyond it's a digital series on Comixology.com and other digital comics sites.
  
  Stuff with Vikings:
  
  
• Northlanders by Brian wood.
  
  
  Other Recommendations:
  
  
• Hellboy by Mike Mignola
  
  
• B.P.R.D. by Mike Mignola, John Arcudi, Scott Allie and various artists
  
  
• Francesco Francavilla's The Black Beetle(HC isn't out yet added digital bundle link)
  
  
• Mind MGMT by Matt Kindt
  
  Also Check out the sidebar's ''Where to Start reading'' section -------------->
  
  EDIT: cleaned up a bit.
  
  EDIT 2: Links, added links to digital version where I couldn't find floppies or HC/TPB that had come out yet. Reading Digital comics on a Tablet is recommended. Dark Horse has their own app, and Comixology has most publishers except Dark Horse and some smaller ones.

This version is broken up into multiple volumes, but is more widely available.

That would be Star Wars: Knights of the Old Republic.
