As for Magic, well, if Ankh Sligh ever starts dominating Type 1 for whatever reason, I've had it called for years. If it doesn't, well, I have fun playing it, that's all that matters. I try to win every game I play with it, of course, but as a strict Johnny, if I'm to win, it's to be with a deck of my own construction (I don't make weak decks, but neither are they top-tier tournament decks). I just don't find it fun to play someone else's deck an win with it.
As for Moss' article, I agree with Kranky Kong on quite a few things: "How about kicking the guy in the shins? That should increase your chances of winning.", etc. (As for that article's Janeway comparison: Janeway wasn't bound by rules but basic ethics). I did give that site a shot after that one article, and it seems Moss has just thrown the worst article in the bunch at us. I also find it silly that the Street Fighter Turbo example with the overpowered Akuma is regarded as a good thing to unofficially ban. It's the fighting game equivalent to a broken TCG deck. If you see the same deck in all of the Top 8, players don't step in and "ban" the deck. People will play that deck to win until the organizers themselves ban it. Just like people "should" be using nothing but Akuma.
Winning at all costs is not the same as playing to win. I'll put into
Richard Bartle's player types: A Killer may be feared, but he knows better than to just attack an Explorer at random. But why? The Killer "plays to win" in a win-at-all-costs mentality, but the Explorer, who doesn't "play to win," simply knows more about the game because he doesn't just stick with whatever's the best. He'll do things other than win. He cares more about learning than winning. This is brought up in some of the other articles on the site Moss provided. What the site doesn't seem to mention in much detail that I could see, however, is that by simply taking the strategies of others, you learn little about the game. The truly great players are the ones who make the archetypes, not the ones who copy it and make Top 8 at Worlds or whatever. At the very least, they're the people who'll proverbially throw a load of crap at wall and hope some of it sticks.
Case in point, I was blowing up local Extended tournaments in Magic a few years ago with a B/W Cleric deck. That's right, B/W Clerics. Beating the crap out of Extended. Was I playing to win? Nah, I was just having fun. Was I winning? Yes.
