Great game idea
I was just thinking, "History of the World" card game. The game has interesting little connotations of little verbages of history and quotations, fun yet educational. To start (starter cards) The game structure is you have a government, a leader, a economic base, a religion base, and a science base. For each one, you can have a starting card, (ie setup. Abraham Lincoln, Communism, Free trade, Koranism, and Historical) So each starting card gives you certain cultural, strength, political, and domination points. You use each type of points then to build your historical tract of your country. The goal is to build the best HISTORICAL TRACT and be the greatest leader, NOT WAR. however, there will be plenty of historical army cards, ie (NAZISM: 1st rule: Laws of Germany) Where you can depose 1 persons government to be replaced. Downeffect, -2 to culture, or something. There will be a pool of cards in the middle to be played and counterplayed.
Here's the turn sequence: Every turn, the History deck, you place 10 cards face up. Each person, depending on their agenda, bids on certain cards to either propulgate their strengths or their historical tract for points. You can have others join you in helping you bid for cards, or you can have opposing factions go against your bids. Whatever the case, you would spend points etc etc.
That's the general idea. Think it's sellable? Card games are a bit over done, but I think it would be a cool collectible game due to the historical value.
