Mega Man's 17th Anniversary

[Storm]

Yesterday, I picked up the Mega Man Anniversary edition for PS2 which contains all of the 8 original Mega Man games. For the past month, I have been absolutely obsessed with these games.

Discuss which of these games (Original and X series) are your favorites, which you found the tougest, your favorite characters and bosses, and which bosses you found to be the most challenging. Discuss whatever you like to celebrate the 17th anniversary of one of the greatest game series of all time.

For myself......

Favorite Game: Mega Man 3 and Mega Man X2
Favorite Character: Vile from Mega Man X and X-3
Toughest: Mega Man X4 (The Final Sigma can be very irritating to kill with X)
Toughest Boss: Violen from Mega Man X2 (The big guy with the spiked ball and chain)
