Concise description:
Make an option for 1v1 speed games that allows for the player joining the game to choose a few of the settings.
Specifics/Details:
1) When someone is creating 1v1 speed game, they most likely do not care about every last setting. Someone may want to play with nuclear spoils, but would be willing to still play with no spoils, or escalating spoils. Let the game host choose the options that he is willing to have some leeway on, and display them for the prospective opponents of the speed game.
2) I only recommend this for 1v1 speed games, because getting consensus with 3 or more players is probably a hassle.
How this will benefit the site and/or other comments:
Sometimes no one will join the exact speed game you have created because people do not like your settings, so you could wait for a long with no game. However, by showing some leeway (if desired), you may be able to attract an opponent more quickly, and waste less time simply waiting for your game to start.
