Um... Yes. I have the Wii as my primary console... XBOX 360 is my secondary console...
I Have 24 Wii Games, 20 of which are mine,
And only 4 360 Games... and only 2 of those are mine!
That's a 6:1 RATIO!!!
Now, keep in mind that I've only had the 360 for about 8 months, and the Wii for 24 months, (2 years)...
But, if you multiply it out, (4 x 3 = 12), then at that rate, the ratio is 24:12, 2:1 overall, or 12:6 per year.
When you've got a 2:1 ratio/year of games, and an overall ratio of 6:1, you know that the bigger number (The Wii) is your primary console.
