For me I'd have to say it would be Sword Art Online Hollow fragment reason being it has a MMORPG feel to it while still being a single player game. It has a 4 player co-op option so long as the 2-4 players are in the same room together so you can get even more of a MMORPG like experience if you have friends who play it and live near you. The graphics are great,the artwork is great, the story just like the anime is great, the gameplay isn't quite as good as the 1st game Sword Art Online Infinity Moment but its still great nonethe less, the soundtrack is pretty good its nothing I'd listen to without playing the game but its still good game music. As far as the graphics,artwork,story,gameplay and soundtrack go being great just like most things its a matter of opinion on whether or not its great or not but in my opinion they are great.
