I mean, they're based on top quality games that, while not a 10/10 in my book, are plenty good enough to earn the occasional 100%. This just adds a few features to it so... I mean if the guy thought it was already a 10/10, I imagine he'd still think as much now.

It reminds me of Mario Kart 8 Deluxe, except that there appears to be less improvements in this instance. A game is rarely going to score lower unless it's a completely botched remaster or something.
