Even with more launching platforms, It won't reach gtav levels, all my little thuggish cousins and my square ass friends copped that shyt. My Facebook feed right now got a whole lotta Gtav comments. They ain't rushing out for Watch Dogs. I don't even think most of em know what Watch Dogs is.
Me personally, I'm more excited for Watch Dogs because, a) the Chicago setting and b) the gameplay looks like something new. But even with my personal excitement I also am very concious about how big of a franchise Gta is.
