First question: It's off-topic.
Vert, you're not the forum moderator around here. But if you really want to be a hard ass, you ought to hit your head with your own book; you're creating unnecessary and redundant threads. Please put your head back firmly and squarely on the middle of your neck.
Yeah, I know you want to encourage discussion, but one thread about the Mario franchise would suffice; no need to spray paint the entire forum with threads about each individual game if it's an ongoing series, especially when we're comparing each game to each other.
Otherwise we're dividing the same discussion between multiple threads, thereby fragmenting the discussion, and making us follow multiple threads for the same topic.
It's like when different comic books do crossovers with each other; you have to collect issues of different series - that you might not normally collect - just to follow and continue the same story. (e.g. Iron Man #67 is continued in The Incredible Hulk #66!) No need for that.
Reminds me of the time - on a different forum - that the same member started 3 threads about the XBox 360 at the same time.
