I don't quite understand how/where which DLCs are included: 'Imperator: Rome' is the main game.
'Centurion Bundle' seems to include the three (?) available expansions.

But when I select both, a message is displayed that the 'Centurion Bundle' is already included in 'Imperator: Rome'...

So is 'Imperator: Rome' already a kind of 'Complete Edition'?

Same issue.

I have the same question. :)

The "Imperator: Rome - Centurion Bundle" seems to already be included in the main game but you only find out about it when checking out. But if that's the case what is the purpose of the bundle, who would buy it and why?

I don't get this GOG weird issues and lack of information, they seem to just not care about selling games, no wonder the company is posting losses.

I'm unsure whether this is actually true though. I purchased the game today and the only DLC with it seems to be the Hellenistic World Pack. I'm also having a problem downloading the installers.

It looks to me like both of these might be weird holdover issues from the time when they offered a "deluxe" edition of the game (all DLC included).

The message displayed prior to purchasing seems to be wrong.

If you buy only the base game , the sub-folder "game\dlc" in the installation folder is empty.
After adding the free Punic Wars Content Pack, you'll find a subfolder called dlc005_punic_pack
in game\dlc.

I think this proves that you have to buy the other DLCs too, otherwise they won't show up in game\dlc.

Are you downloading it via the Galaxy or standalone installers?

Standalone installer.

Edit:
Galaxy adds this:
dlc001 - Digital Deluxe Edition - Hellenic pack
dlc003 - Extra Content - OST + Artbook + Wallpapers

If you try to purchase the "Imperator: Rome - Centurion Bundle" while already having the Imperator: Rome base game (not the Deluxe version just the base game), at the checkout the following message is displayed "Please note that Imperator: Rome - Centurion Bundle is already included in Imperator: Rome which you own.".

Based on what you are saying:
- It looks to me like both of these might be weird holdover issues from the time when they offered a "deluxe" edition of the game (all DLC included). - kozlodoev
- if you buy only the base game , the sub-folder "game\dlc" in the installation folder is empty. After adding the free Punic Wars Content Pack, you'll find a subfolder called dlc005_punic_pack in game\dlc. - surfer1260

... It is pretty clear that the displayed message is incorrect, the paid DLCs are not included in the base game and would have to be purchased. Thanks guys for testing it and taking the time to reply here! :)
