I picked the $1.99 package, which would be 350 thousand worth of play money. You can buy more play money, which is ironic, but can get you playing in the bigger play money games.
Outside of problems someone might have had with a deal or hand, the only other problems would be with purchases. The problem with is how they handle problems the members might have. They usually seem to treat each hand as if it is real money.
Now it is more relaxed and there is not so many players that raise and go all in, all the time, because it is play money. I like the playing of the game, I re-installed it after a few years of not playing it. but that is okay for me because I only ever did use the play money feature.
