My Gaming Skills... Ineffective!

Whew, I just picked up the Mega Man Anniversary Collection for PS2, and Mega Man 2 kicked my ass. I grew up on that game, so what gives? Am I so out of shape? Have my gaming skills really gone that much to pot? No wonder I'm doing so badly at Metal Gear Solid: Twin Snakes, Ikaruga, and Mario Golf--just to name a few. I seriously need to log some time with the blue bomber to revive my gaming skills from the candy-assed shape that years of RPG dedication has left them in. Good grief, man, pull yourself together!
