The data for those is being updated, we're going to be doing a rerun of the data before 24 hours have passed. The way it works is, top-voted game that you could only play on that system as released that year. We tend to ignore other years when calculating this, partly because it helps streamline data entry significantly. You could think of it as "new exclusive." So for instance, Rocket League was new on XONE this year, and only XONE (as far as I can tell), so despite being released on PS4/PC previously, those platforms don't matter re: this category.
That category's data has been updated and will probably look like Rocket League, Raiden V after all is said and done. PS Vita's category is also being updated. The update should be up within 24 hours.
We COULD alter how we rank those, but: it would require extra data that we did not and have not ever collected, and it would be a change from previous years, something we give serious thought to do before doing because it affects the usefulness of year-over-year data. That said, your point has been noted and it will be something CM and I discuss as we always discuss GAF feedback to continually improve the results.
