I've been running a pretty healthy alternative to the SteemSports games. I have a smaller audience, but the payouts are much larger for the winners and my cut is mostly limited to the SP award. It's not a "distribution" game, per se, but it does distribute and I have a loyal group of players/sports enthusiasts. Competition is good, so I'll be looking at new ways to expand what I'm doing and will take some of @dantheman's ideas into consideration if I do decide to branch out.
