The Final Age is an area majority drafting game.

You have 7 cards, you play one, draw one, then pass along the hand.

You try to place armies on a map by what you play; but there is also effects based on what areas you control and what cards you play.

You have a majority by managing to add 5 armies to an area before someone else. Someone else then have to move an army inside that area with greater than 5 to take it back - which is hard to do because the cards can never add more than 4 (but can move from A to B).

perhaps the cards should use a double side like in DEWAN.

Perhaps the cards are two handed, like in flamme. So one hand determines army and the other hand determines location. With some basic effects on some cards e.g. move army from X to Y.

the players don't have a color themselves, but rather the way it works is by stacking discs in the areas and whoever stacks 5 can then place their ownership disc on top which makes it "owned". They may also move an army from a different location to stack a large combo on top which gives them bonus for every additional disc on top of the 5 before it is " shut down ".

extra rules.

like in 7W each player has special moves or scoring incentives on their " plate ".

like in Rebirth each player has the means to collect mission cards for secret objectives?

The three stage thing in 7W is fun but I think perhaps just RNG cards like in Ohanami is better overhead. Alternatively that the game is a continuously draw and play. So you all pick your combo, then reveal them and take action based on moves. Then draw new cards from the draw piles before moving to the next pick a card and play it phase. But it sound tedious, maybe better to just do 3 restock of cards like Ohanami.
