I have been meaning to do an VGChartz 7th gen ratio comparison since I first did one for the Wii, but never got around to doing it due to laziness. Recently returned to it, WPCT has prompted the idea, and decided to do undergo a 7th gen comparison!
Keep it retail only, you can do digital as a bonus. If you only bought digital you can add your equivalent downloadable retail titles in your ratio.
Here's an example of voting:
|40% first party
Nintendo - 4
Capcom - 2
Ubisoft - 2
Sega - 2
First state your percentage clearly so the post votes can be easily counted... and that's it really.
In one week's time I'll update the OP with a poll/post votes comparison. And later I'll make the 7th gen comparison on Gaming discussion with only the post votes (hopefully there will not be that many posts :P).
P.S. There's also a current gen WiiU thread: http://gamrconnect.vgchartz.com/thread.php?id=188993
