Who do you respect more as a gamer?

Let's say Person A is someone who plays tons of games from start to finish (or at least a majority of the way through the games he plays), but once he's completed a game, he's done with it. This gives him more time to devote to even more games, and as a consequence, he knows lots of the major details about a ridiculous number of games from almost every genre. If you have a common question about a popular game, he will most likely know the answer. He's also up to date on new releases and plays games as soon as they come out. However, he often doesn't bother with "perfecting" the game and may skip optional sidequests.

Now let's say Person B plays far fewer games than Player A, but this player knows way more about the games that he plays. This player will likely play through the games multiple times while doing all the sidequests. This player will likely attempt everything the game has to offer, and will often impose challenges on himself (low level, no deaths, default equipment, speed runs, etc.) to maximize what the game has to offer. If there's a multiplayer component, Player B will likely be very good at it. However, if you were to just select a random game, it's possible that Player B hasn't played it and won't know anything about it. Player B may also restrict his interests to a certain genre or company. Player B will often continue to play games despite their age, and probably won't get games when they are first released.

Who do you respect more as a gamer? (or if respect is the wrong word for you, which of the two you feel more represents a gamer in your eyes)

Jam it back in, in the dark.
