near the end, just before the FAQ in the rulebook, it talked about simultaneous actions and when certain things are played that involve other players.
Most of the players’ actions in the game are performed simultaneously. However, there are cases where timing issues arise.
Whenever a location’s ability asks the player to do something regarding another player (for example, take credits from him), that action is carried out after all other players’ actions are completed (build a location, discard for credits, build a Reactor) unless specifically
stated otherwise. The same applies when Conflict Cards are played: Their effect resolves after the other players have played their card
for the turn.
Whenever 2 or more players want to do something at the same time (for example, use their Racial Abilities or play Conflict Cards), they
do it in the order their Player Markers are on the Score Board. The player with the highest score goes first, then the player with the second highest score, and so on. If both players are on the same spot, then the one with the most credits goes first. If they have the same
amount of credits, then the order is chosen randomly.
