I hate it when that happens too. If I lose, I'll sometimes stay around to watch the other players and figure out their poker style. It can be very useful if you play them again in the next game. It's always frustrating in any game when the host is losing
so they just rage quit and it ends the game for everyone. Some people are just sore losers.
Yeah, poker is still really active. You'll sometimes get an xp reward if you are the runner up in a game, but only the winner collects the cash. Some of the achievements for gambling are rather challenging too. Should keep you playing for a while.
