The play is pretty good in that players fold about a third of hands and call/raise 2/3 of the time. 3 cards and a side bet that can pay 8000-1 give it enough IMHO.
The game is simple.maybe too simple, like 3CP, but the added feature of 7 cards vs. I would disagree that the game is going to be gone and think Galaxy actually has a pretty good game on its hands.
