Has any established gaming platform that has ever existed (except for maybe the super early ones) made game-collecting a thing? Trying to play every game on a console is a silly and pointless fools errand -- yeah you could do it, but there's no inherent value. At least to me, it seems like the value-add for a system like this is to effortlessly play games with your friends, and then maybe to check out some console exclusives that represent interesting gameplay. Who in their target market wakes up and says to themselves "I need to play every game ever released for this new platform"? They're doing lifestyle segment marketing already, hence the smiling clean-cut millenials sitting and enjoying quality time together, they're encouraging me to want to be like those people, but then I read the line and instantly asked myself "why would I want to do that".
Just seems like the marketing team took the wrong turn on the road to being different. Maybe I'm totally wrong, and I'm just one data point, but also, maybe it's that that line that was awkward.
[EDIT] - On second thought, my original post was badly phrased. It's not the "weakest tagline I've ever heard", it just seems to massively NOT fit the context/platform/product.
