I agree with you with magicdice as the house always wins and the long term you end up losing. But the games like @steemmonsters and @drugwars are investments in my eyes and you are getting in at the start which will increase your ROI by a higher percentage. The last two days on drug wars I am after been paid 12 steem for playing. That's massive . Users increased to 1200 and you know when they are doing something right when all the major players are in there building their empires.
