The Escapist isn't exactly Encyclopaedia Grammatica. This website doesn't demand the kind of bibliographic exactness you find in academia and readers don't expect it. Regardless of the holes that exist it's a fairly sound statistical approach; you take all the data you have available and you average and range it. Even with subjectivity and error margins in individual reviews, this kind of approach is effectively averaging almost every online launch review score ever. It's reputable, reliable data (a lot of calculated data from reasonable sources). Its conclusion (if a little badly worded: "had worst launch games" is misleading) only says that average launch scores were worst for the WiiU and that is perfectly valid. I totally understand what you mean about holes, but you're picking out what basically amount to minor deviations with that amount of data to go on.j-e-f-f-e-r-s said:Oh my goodness sweet Jesus... really? Really? This is what we're considering news now?
Regardless, even the biggest worry in that list (if you ask me), the older entries like the PS, doesn't mean the whole graph is worthless. It just means you take what it says about the PS with a grain of salt. It's not a yes/no question.
And last of all, so what? No consoles are judged in the long term by their launch lineup. The PS3 was a fairly bare, highly overpriced system when it first came out and look at its performance now. Even if you believe that the WiiU launch titles aren't that great, it won't matter a few months from now. This little graph isn't that damning in the long run, even if it were 100% accurate.
