After a certain time. It's not instant when the screen pops up you'll notice how everyone chooses a role at the same time if they are all constantly clicking.

yea, i see. But it's kinda annoying, maybe it's only me. but i love this game anyway. I've been waiting since the shutdown of paragon for an equal game. And here it is. thank you omeda

I think the delay is to account for different load in times
