Council is a 1-page x-comlike video-conferencing game. There's also elements of Pandemic in the mix, and everything is run off of a deck of playing cards (which is controlled by the GM, to avoid everyone having to duplicate deck changes on their side of the screen.)
The initiative rules are a little odd and unclear (suit drawn decides who gets to take a turn, which implies that you should have exactly four players, no more or less,) but it's fairly easy to just house-rule that the turn order rotates and that the kind of turn you can take is determined by the drawn card's suit.
Overall, this game does a fantastic job of miniaturizing/streamlining x-com and pandemic into something that can be played through in half an hour.
It's also solo-play compatible, and makes for a short but crunchy timekill.
This might be my favorite one-page game? At minimum, it's impressive, and if you like anything I described, I strongly recommend checking it out.
