I'm addicted to WSOP iphone
app and Xbox Full House Pro. Both have SnGs where a few idiots burn out at the beginning but then it settles down into something more like real poker, ring games are a total waste in my mind.
You will see every bad beat imaginable and innoculate yourself a bit to the emotional ups and downs, you get to practice your odds calculations a lot.
I've got 30k hands between the two apps. Once online poker goes legal in Cali, I'll let you know if it was worth the time invested!
