Exactly my problem. I love complex games, but I have short batches of time, mostly without full energy, and undetermined amounts of breaks between them. A full fortress mode DF is too much for that. Even if the learning itself is considered fun, it's just not possible due to the long breaks between sessions. And it's not true that it is impossible to deliver content in that way. Even stuff like language learning is possible to put into waiting-5-minutes-for-bus sessions on the mobile phone. Last but not least, there are games that can deliver on that. CK2 is somewhat playable, droppable, and still fun. You also _can_ choose to put additional hours and energy in it to make it more complex and more fun. But simple is possible as well. E.g., only now, after maybe 4 years of owning the game, and about 116 hours logged in Steam, I _start_ to learn about the Papacy and using religion to my advantage. Until now it was just like a random event, something that happened on the side but I didn't have to bother with too much.
