This is really a pacing question, but there's no tag for that:
The general concept is that the players are working in a team and need to be able to react to eachother's movement and observations as they happen(not being turn based) without the game having to be played at a real time pace.
This question and it's answers offer some insight: Turn-based strategy games where action happens in real-time? But I'd like to implement it so players can change their queued actions on the bases of realtime stimulus.
Right now my thought is to use an action queueing system in which the players can state a series of actions they intend to take and actions are played out simultaneously until one player runs out of queued actions or certain triggers offer a brief "change your queue" period. It seems like it would be clunky and leave players waiting a lot of the time.
Any bright ideas to make this possible while still enjoyable?
