Sometimes all you need to make an enjoyable game is just a few simple choices. In Starfall, when it is your turn, you only have 3 choices you can do with your one action. Those three choices are putting out a new disc into the sky, decrease the value of one of the discs already in play, and then lastly you can use your stars to buy one of the available discs.
Each of the discs have different spacey elements shown that score different. If you get lots of comets each of them slowly grows in value. You can get some planets for moons but each moon has to have a planet. (Evidently no multiple moon planets in this galaxy!) Others are just worth stars that can be used to buy other discs.
While the game has very few choices, deciding which one to choose can be a thinker. Putting out a new disc you want to buy might not last until your turn. The decision between making something cheaper or just buying it is one of the hardest to make. You have limited currency to spend on getting discs so you want to get your bang for your stars, but if you make it cheaper someone might buy it first. It doesn’t help that sometimes if there isn’t room in the sky you could be making it much cheaper than it already was.
Starfall’s simple choices that require thought is why it is one of our favorite games to teach. People can start playing in less than a minute and then have the fun of making those tough choices throughout the game. Just don’t ignore the comets - if someone gets a lot of them they can sneak in a victory!
