Units from culture packs and campaign packs - how do they work?

[Jaśko]

First - I'm sorry, I know that information is probably somewhere to be found, but I tried and can't find it :<

So I know culture and campaign packs both unlock some playable fractions in the grand campaign. However, if I don't get the DLC right now, will these fractions still be there in a grand campaign, played by AI?

In other words:
1. Will I encounter Saba or Nabatea in grand campaign without buying Desert Kingdoms Culture Pack?
2. Will I encounter Nervii or Galatians in grand campaign without buying Caesar in Gaul Campaign Pack?

Yes you will. Opposed to campaign expansions, culture and unit packs are just cash grab paywalls. All the content is in your game, it's just locked. The AI still has access to it.

Maybe not the greatest business practice, but at least it's good to hear I will have a full gameplay experience with Romans and the other starting factions. And maybe later get one DLC at a time if I enjoy the game.

Thanks for the answer! The game is already downloading :D
