An SRK Review by "Red Rick Dias", which has no score, but states: "In the end, $50 will net you a fine 2D fighter with a varied roster, excellent pacing, and the inclusion of several ‘quality of life’ touches to make things easier for tournament play. The King of Fighters XIII can definitely hold its own against more established games in the genre, and deserves to be in your library."
His impressions of the netcode:
"I was able to play several matches against an Atlus representative for this review and found the online play worked fairly well. Both of us were landing decent combos, able to react to hop attacks, block alternating high and low attacks reliably, and so on. These aren’t bad results for a match between two players halfway across the country from each other, so I suspect it will be at least passable for most people. It’s true that no online experience will be perfect (such is the nature of the beast) and this was a test under only one set of conditions, but the results were encouraging."

A review from "VentureBeat" which gives it an 85 out of 100: this is one of the strongest and most relevant entries in the 15-year franchise. I won’t lie, the upgraded visuals are a substantial driving force in my championing of this game, but there’s also an undeniably deep and more importantly, enjoyable, experience under the surface. I believe that not only will fans love it, but it may be the game that finally snags a few newcomers as well.

A direct feed vidcapture of an HK online match, that claims it was a 3 bar connection. It looks amazingly smooth, and these guys don't seem held back by the connection in the slightest.:

Not to mention the load times seem to have totally disappeared, and the uploader claims he didn't do any editing, just installed it...
