Try at least Rurouni Kenshin : the 1996 95-episode historical action romance TV anime (accompanied by a 1997 movie spinoff, a 1999 4-episode OVA prequel and the 2001 2-episode OVA sequel, not to mention with the 2011 Kyoto arc HD retelling 2-episode OVA) sets in Meiji Era. It follows Kenshin Himura, a samurai recognized for his cross-shapped scar shattered on his left chick. He wanders from city to city until one day he meets a young female kendo teacher named Kaoru Kamiya. Kenshin possess a reversed sword, however for some reasons, he cannot kill people. He must face many ennemies, including the ones who know him in the past. It's pretty well-known and really stoods out the more generic shounen action series. Its fillers were really enjoyable despite being really present at the end of the series. The OVA are really considered as "masterpieces" due to awesome animation (despite the story is more rushed than the TV series, especially the second one). The Kyoto arc was the best arc in the TV series as well.

If you like Code Geass, you should also try Guilty Crown : the 2011 22-episode (only 15 are released out so it's ongoing) TV anime sets in a futuristic world contamined by the powerful crystallized virus. Shu, a 17-years old highschool boy, possess a ability by stealing others' weapons contained inside, in order to rid out the virus. The series follows how Shu must protects the people he loves. It has good (if not great) animation and excellent music, but the plot was filled of pacing problems (despite its unique concept), clichéd and one-dimenssional characters, ridiculous (but less numerous) fanservice and terrible (but decent) CG. In order to not be dissapointed, watch this before giving Code Geass a shot.
