whether a game fall sinto A or B really depends on the person playing it. I wouldn't ever really classify any game as being only A or only B... but like... scales maybe. Like you can have a game thats say... 3/10 A and 5/10 B. They aren't supposed to add up, just sort of measures against the rest of the games in existance. like consider it as percentiles. This myster games is better than 30% of all games if treated as an A game, but better than 50% of all games if treated as a B game. Something like that.
I tend to think of A games as... entertainment that is crafted so intentionally and so well that no random aspects could ever compare. The downside being of course that you lose replayability. I tend to think A is better because of that human touch of craftmenship.
I think of it like say... riddles. I love riddles in video games because of how cleverly designed they can be and how I have to often think so hard to realize the solution. But a riddle is a one time thing. Once you know the answer, the riddle can never be fun again. But I find that 5 minutes of riddle solving to be better than any amount of replayability that could have been substituted in its place.
even something like monkey ball for me... the singleplayer is an A, and the multiplayer is a B. I did everything there was to do for singleplayer. Master mode, all of it. And it was a one time thing for me. Once I had seen every level and thought of a way to master it, thats it, done. I've never played the game since. For me SMB single player is an A.
but many treat it as a B. Replaying each level trying to get faster and faster times. I find that utterly boring. Its not for me. But the game appeals to both types and so there is something about the gameplay that is simultaneously A and B.
or I guess a better example would be diablo 2. I thought that was a good game, but again, its an A game for me. One time through in single player, I saw the story, beat the game, the end. Never wanted to play it again.
so obviously, I treat every game as if its an A game to begin with, and thus, games that do A well are generally going to appeal to me.
