Predynastic Egypt problem with 2K (ended)

Hello, just wanted to inform. Pre-Civilization Egypt and Marble Age have both been removed from steam store actually because it contains the word "Civilization" in Pre-Civilization.
Here the dev's answer : http://steamcommunity.com/app/461620/discussions/0/215439774862269688/

 Valve, 2K and Pre-Civilization (our games are unavailable in store)

 Dear players! The Valve has informed us, that they have received claims on behalf of 2K, Inc. that our games (Pre-Civilization Egypt, Pre-Civilization      Marble Age) infringe 2K’s trademark for “Civilization.” And they have removed these games from the Steam store while this matter is under dispute.

 We already contacted 2K representative regarding this mistake and we hope to resolve this issue soon. Why we think this is a mistake:

We can’t find the registered trademark “Pre-Civilization” in attached XLS documents with registered 2K trademarks.
In dictionaries and science literature it is an independent word meaning the time prior civilization (that exactly our games are about). http://www.yourdictionary.com/precivilization
And we pointed out that for example Galactic Civilizations series may have the same problems with in future in this case.

 We’ll keep you informed about this situation. 

Hello... i hesitated to post this here shy i'm not sure promotional giveaways for a game are well considered.

Devs asked people to help him translate the game to multiple languages and i volunteered.
He gave me 3 keys for friends... One went to a friend, another to a group of friends, and this is the third... To friday next week.

Oh ! What is the game ? I've not tried it yet much in reality. shame
It's a strategy game about ancient Egypt. An indie game but very beautiful.

(edit : thank you very much for your super nice feedbacks)
