Pictographer

If you love languages and their evolution like I do, this game is perfect for you.

Submerge yourself in a fictitious society of your creation and give them the spark of language through pictograms of your own making!

All you need is a deck of cards with the jacks, queens, and kings taken out, a pencil, paper, and as many friends as you want (could be zero; playing solo is a perfect option).

Not to toot my own horn here, but this game is also great for short amounts of time, for there is no continuous narrative, and it can be played for however long you have. After a session, you can save it for some other moment;
no story will be broken.
