As we probably know, Million Arthur Arcana Blood is more or less the forth game to come out on Nesica X Live 2 service in the arcades. It is the second major one besides King of Fighters XIV. There might be releases of other games on that service like Ultra Street Fighter IV and Blazblue Central Fiction but that doesn't count as they were originally released on the previous-gen arcade system so to Playstation 4 and Xbox One, they are one-generation behind as if they can be ported to their predecessor consoles.
Originally, the Million Arthur series started off as the card battle game on mobile devices and the first one happened to be released outside Japan although the later ones had some Asian releases. The series is so popular that it has other media contents like the short-animated spinoffs which can be viewed on Square Enix's official account or something and especially the upcoming spinoff arcade fighting game. Similar to Nitroplus Blasterz and Dengeki Bunko Fighting Climax, you can summon Knights through their corresponding commands in addition to using special and super moves belonging to the playable character. Some of the characters don't have the actual names and are therefore, named as the type of Arthurs. You'll rather want to go for the good type of Arthur although the Thief Arthur is somewhat one of the fan favorites.
There are several game modes so far like the Local Network Match, Online Match, Story Mode/Arcade Mode, Training Mode, Tutorial Mode and even the Friend Match which is something I don't know of. And since this is the first arcade-exclusive on Nesica X Live 2, it can be more a challenge for players going for Single-Player modes. I don't know if you'll get interrupted by other players jumping in during those modes or not.
From what I saw from Baba Game Center Mikado's official YouTube channel, the interface of Nesica X Live 2 game selection screen has some elements similar to the Steam game page. There may be videos and screenshots to preview of course. I'm not sure if Steam TV Mode or Steam OS has similar stuff like that like you can see videos and screenshots of whatever game you're looking at. Right now, the game still has yet to be released and hence, the location test progress according to the latest update. Normally, during game location testing, the game is still in prototype form and video filming and phototaking of those games are not allowed. Not even video capture is also allowed as well but somehow, that arcade center has the rights to show the location test version in action. There are other gameplay videos of the game prior to the release date in Square Enix's official YouTube channel. Even the opening video from that channel has a confirmation that Team Arcana of Examu is the actual developers of the game. Before that video existed, I already had a guess that Examu might have developed it with Square Enix being the publisher probably due to the fact that the game has the word, Arcana, in the game title and it's a fighting game. Other fun facts included the assets and elements taken from other Examu games as well like Nitroplus Blasterz, Arcana Heart, etc.
The graphics are more or less better and on par with Arc System Works fighting games with 3D backgrounds and 2D sprites although the overall mixture makes them one generation behind like the game could have been suited for Playstation 3 and Vita releases. Blazblue Cross Tag Battle is also guilty of having previous generation era graphical assets but from the recent character reveal video from Arc System Works' official YouTube channel, the Distortion Drive/Super background is changed. Like Arcana Heart 3 Love Max, pressing ABC activates something similar to Extend Force which changes background.
The release date for the game will be 21 November in Japan.
