Round based games, wait for players etc.

Hey guys, is there an easy way to create round-based games. One in which the game wont start until there are at least N amount of players ready. And that when the round starts, no one else can join, only in the new round etc.

Cheers,

I think the short answer is no if you want to do purely blueprint ones from scratch. But from shooter example with C++ then yes. The reason being that possession of server/client is not really clearly defined in current engine code, some of the base classes you can still see shooter based functions(StartFire to trigger respawn, and some condition check for isWaiting/isSpectating) instead of purely abstract method, guess we need more time.
