They're made by the same manga group, and it stars the same characters but just in alternate universes.

Saki

Who will be the King of Game-er no, I mean the Champion of Mahjong. Basically both have similar worlds where apparently everybody plays Duel Monsters or Mahjong. Also Dumb Luck/The Heart of the Cards take a large part in both of them and somehow Yugi and Saki are blessed with them. But prefer Saki because this teaches you about a game that actually requires strategy and you get more women. Also Saki has unbelievable amounts of kinetic yuri!

D.C.II S.S.: Da Capo II Second Season

They're both harems with a touch of supernatural and the main characters are just lovable assholes. The greatest similarity between them are the opening scenes, where "a certain character" talks about their dreams. If you liked Da Capo II Second Season, I would totally recommend Kanon 2006 since it is basically better in every way. (Ex: character development, animation style, story telling, etc)
