Oversaturation of the paradox market,they have four games with endless DLCs. Even the most hardcore fans are getting annoyed at the endless dlc. Having too much games deludes their market niche and turns people off. I am truly amazed at Paradox people,they are next level incompetent. Should have fixed they games and gathered some good will,a full 60bucks CK 2 package and stop developing dlcs for the game,plus repackage of EU4 making a 60 bucks for the game and all the content DLCs exepth the newer ones. Don't know if this level of retardation is native to the Swedes.
Another thing is that Rome is kind of overused. There could be done a lot of interesting things with it,but paradox lacks the talent and the will. Meh,SJWs,wouldn't be surprised if Egypt is filled with blacks of arabs.
Their share price skyrocketed from SEK 33 at the IPO to SEK 200 in the last 2 years, so financially, they do extremely well. Their revenues also double all the time, so, like it or not, they know what they are doing.
But I agree, that I don't expect Rome to become a CK2 or EU4 type of success, even though personally I'm more likely to buy it rather than EU4.
Paradox says they won't do small titles like Sengoku again, because they didn't sell, so they certainly aim higher with Rome, but I think it will turn out weaker than EU4 (brand) and CK2 (unexpected major success because of the youtube friendly character / emergent story focus).
The name is also kind of misleading, it's not a game just about Rome, the map stretches from Sweden to India and the timeline seems to allow a focus on the diadochi.
