I was introduced by Devil May Cry 3, by a friend at boarding school. A lot of us would hang out in his room and play it when he first got it - eventually it dwindled down to me and one or two others, and I just asked if I could borrow it. It took me 13 hours to beat normal with all powerups, and the others taunted me for taking so long, but I loved the game. When I got some money freshman year, I bought both 1 and 2, and watched the anime on youtube.
However, I wanted to play the games in order, so I was stuck on 1. And I sucked. It took me until a week ago to beat Phantom without using items, but then I got used to the game and got all the way through it. I finally played 2 and 4, and while they're not as good as 3, I don't think they deserve most of the heat they get.
