Now that we know what the software and hardware sales are, what about the spending habits of the gamer? In other words, how many games does the average PlayStation 3 and Nintendo Wii owner game? The NPD Fungroup estimates that the tie-in ratio for both the PS3 and Wii are fairly close, actually. In January, the average PS3 owner owned 2.7 games, and the average Wii owner had 2.2 games. For February there was a notable increase, as the numbers shot up a point. Now, the average PS3 owner owns 3.4 games, and the average Wii owner has 3.6.
