The gamer that has affected the way I play the most is my brother. The reason is that he is the one who introduced me to role-playing. My brother ran me through Keep on the Borderlands. It was his stack of AD&D books and modules that I used to read. It was his Grenadier miniatures that I used to play with. Even though he killed my 1 hit point wizard (which made me cry), he was my first model for role-playing.
