If you liked the Code Geass: Lelouch of the Rebellion anime, the Anime-Planet community thinks you'd like:
Cross Academy is a school with a difference: in a unique and experimental setup designed by the headmaster, it has a Day Class consisting of ordinary humans and a Night Class filled with vampires. Yuki Cross and her friend Zero Kiryu are school prefects whose job it is to make sure the secret of the Night Class is always safe; they patrol the school grounds at night and supervise the switchover of classes at dawn and dusk to prevent any 'accidents' from happening. While Zero is suspicious of vampires and hates the idea of sharing the same space as them, Yuki admires the Night Class for their beauty and sophistication; she is especially intrigued by their charming leader, Kaname, because he once saved her life. However, as Yuki quickly learns, not all vampires are amiable like the Night Class, and as terrible events unfold, Yuki must ask herself whether in a world where vampires are the hunters and humans are the prey, peaceful coexistence can really be achieved.
The character of Kaname in Vampire Knight is very similar to that of Lelouch from Code Geass. They have the same dual-natured, tortured past, plotting, clever chess playing personality, and the plots of both animes are structured around their schemes.
Having recovered from the injuries he had sustained, Zero returns to Cross Academy to resume his role as prefect. Though, not long after he resumes his role, members of the Supreme Vampire Council ambush Zero with the intent to execute him for the murder of the pureblood, Shizuka. Luckily when Kaname intervenes, he sends the council away and insists that they stay out of school affairs. However, whilst Kaname continues to hide the truth about Shizuka's death, there are others who grow suspicious of what happened that night and what the dorm president is hiding. Meanwhile, Yuuki begins to have flashbacks, leading her to investigate her blood-stained past: what will she find, and will she continue to be tempted by an offer from Kaname?
Vampire Knight and Code Geass share very similar characters. The male leads, Kaname in particular, are structured like Lelouch--clever, conniving, and tortured. However, the protagonist in Vampire Knight is female which shakes the dynamic up a bit. Both animes center around the plots and schemes of its main characters, and...the inevitable chess board.
Ever since Yugi Mutou completed the Millennium Puzzle his life has changed; he's made friends, learned how to play the card game Duel Monsters and has gained more confidence in himself.

In order to retrieve it Yugi must now participate in a tournament against the best duelists in the world, defeat the game's creator, and learn more about the secrets within his Millennium Puzzle!
I know this my be a bit of a strich but bouth series revolve around a highschool student obtaining a magical power and using it to try and make there loved ones lived better. for lelouch his sister and for yugi his grandpa. Also bouth involve a lot of stritegy in the plots and both have simmiler animation and good charecters
The hostility between Earth and Mars has grown, and a war is drawing close. This, however, does not concern James Links, a rough American cargo hauler who wants nothing else but to patch up the relationship between him and his family. But things change when he discovers the highly sought after orbital frame Dolores, quickly causing himself and his two teenage children to be framed for murder and accused of terrorist actions. Follow them on their journey to Mars as they try to clear their names of these crimes they did not commit, with only each other to rely on.
Zone of the Enders: Dolores (ZOE:D) also mixes up action, drama and a pinch of comedy to make for a fun, fast-paced show. Also, if you loved how Code Geass kept sticking characters in a moral grey-area then you'll be glad to hear that ZOE:D has this as well. Both series also have a rather unusual protagonist as far as anime goes. James even moreso than Lelouch. I mean: How many anime do you know in which the main character is a 49-year old widower with 2 grown-up kids?
There are, however, a number of differences I'd like to note.
First off, while CG tended to have scheming and political machinations when character weren't fighting or engaging in comic routines, ZOE:D opts for being more of an 'adventure' in which the heroes end up having to do all they can to stay out of the villains' hands.
Second, ZOE:D's art and animation isn't quite up to par with that of CG. It may take some time to get used to, but once you are you'll enjoy the series just fine.
And finally, while CG's first season has gained notoriety for its cliffhanger ending. ZOE:D's storyline is completely finished when you're done with the last episode. Leaving the viewer much more satisfied.
