This is actually true.  IO have learned alot about my friends Playing Magic: theg athering.  For instance.  One of my friends is very strategic and cunning. to be honest I knew this from the begining but not to what extent.  In Magic he often bluffs.  However, His bluffs are the exact same as his confidence.  I realized while playing him that he is very manipulative.  He could tell you something 100% wrong and make you beleive it without providing any acurate information. I actually lost a game of two headed Giant (two on two match for those who don't play Magic) and he and his partner played Goblins, me and my partner played something else.  I cant remember.  However, I want to say this.  my friend left a mana or two out.  Goblins dont run on playing spells often unless they are burn spells.  Had we attacked he would have only killed a 1/1 creature seeing as any burn spell that costs 1 mana does....guess what, 1 damage to target creature or player.  my partner resisted from attacking while I said to atttack.  Safe to say we didn't attack and I caught my friends Bluff.  It was another goblin in his hand andn ot even a spell. 

On the other hand.  My partner, another friend, plays very conservativly.  He doesnt attack often until closrer to the end.  He's a very definsive player.  What he prefers to do is save up and save up until there is no way you can hurt him.  He plays elves that act like Spawners.  The more you have down, the more you get on the field.  He has some that create token Creatures.  I notice that in RL he tends to be very conservative at least with money.  I understand why, most of his money goes towards being able to see his Girlfriend who lives a state away. 

Now, I have a third friend who sucks at the game, but there is one thing I notice alot (I shouldnt say he sucks at the game he jsut cant seem to grasp how to build decks.  He plays very agresivly and gets pissy easily.  Safe to say I enjoy beating the tar out of him.  He claims he can beat me but I have yet to see him win against any of my current decks but perhaps once when I got screwed out of mana.

I have a third friend who is just evil when he plays the game.  I mean I never knew how evil this guy was.  He's scary when he plays.  However, he's pretty mellow and tame outside of dueling.  I wonder now...wich side is his true self...the Vamperic Duelist (He duels with Vampires btw) or the Mellow civilian. 

As for me.  I don't know how I play or if I even put any effort in it at all.  I can do a 3 way duel, but barely.  My friends and I often play 4 or more and I have attention span isues there.

Outside of Magic, and into WoW.

Well only my first and last friends play world of Warcraft.  The other two don't.

Now, the first. He is, as you have guessed, Very strategic. Now he does enjoy fire Emblim alot and loves those games.  In WoW, he is often the Leader Tank.  He leads the gorup into combat and protects everyone very well.  Another thing I should point out here is that I learned while playing WoW is that he is a protector.  He'll watch your back and take a hit for his friends.  I honestly beleive that he would do the same in Real life. 

Now the other "friend" whom I only hang out with because we see each other at the Game Cafe I go to, acts very noobish.  He sits there a complains when somethign hapens and often he does nothing to help.  Now he'll do the same thing in Real Life.  He won't take blame.  He claims he was completly innocent and had done no wrong.  Safe to say why I only hang out with him in public.  I got tired of hearing him whine and complain, and then contradict himself at the same time.
