I already own or have owned 18 out of those 30 games so I guess I won't buy all of them but I buy an average of 6 of the top 10 sellers on each system.
Also taking into account I own all three systems but never buy the same game twice (As in I choose which system to buy each game on) the percentages are higher.
It really is scary how much money I spend on games!
