Yep, and it's tough to choose at the outset. Origins still has a ton of enemy forts and such that you'll also consider it as filler by the time you're through, so with both games you do as little or as much side stuff as you want.
If you have the time and are going to play both eventually, I would say Origins first. Though shorter than Odyssey, it's a huge game on its own, probably super cheap by now, the spectacle of Egypt in this game is fantastic, and the story is ultimately worth experiencing.
I still need to play the Origins DLC, then go and play the Odyssey DLC. I'll definitely have a good time with both.
