To avoid letting down your friends, you are obligated to play when you don't want to.
"Notifications will tell you that your friend is waiting for you to play or that they've nudged you or that your game is about to expire. This is true of strangers as well who have challenged you to a game."
"Guilds generally require participation, and high-level guilds especially will demand constant play."
"There is a guild system with a "Guild Run" that can be done every few days that provides unique rewards."
"If you start a game with time limits of 1 day per turn, you need to take a turn every day. It allows you to select a slower cadence or no time limit though."
"Players can share their servants with other players, and you are rewarded whenever somebody uses one of your servants. The game's frequent events encourage players to change their support roster to fit the current event to provide other players with relevant bonuses. As you can only have a limited number of friends, it is beneficial for players to unfriend people who are not playing regularly or updating their support roster."
"Players join guilds Guilds are then ranked against each other There are multiple "guild battles" per week, in addition to a timed ranking of guilds called Palace Celebrity"
