Personally, for me, I found the Metroid Prime series reasonably challenging. By that I mean, I never really had any problems against any bosses besides maybe Metroid Prime at the end of the first game, but Metroid Prime 2: Echoes and Metroid Prime 3: Corruption I found rather easy. In contrast, I can't get past Norfair in the original NES incarnation of Metroid. Metroid: Zero Mission was fairly simple until it came to Kraid, Ridley and Mother Brain... Mother Brain in particular is hell in Tourian. I haven't fought her in Super Metroid, but Metroid: Zero Mission's addition of an attack (whereas before she'd remain static) combined with the (annoying) turrets and relentless Rinkas has changed my view about videogame difficulty entirely. Once you get used to the control scheme in Metroid Prime 3: Corruption (if you've played the first two and are used to the GameCube control scheme that is). Although, in order to get everything in the game it is challenging, but even on the hardest difficulty in Metroid Prime, Metroid Prime 2: Echoes and Metroid Prime 3: Corruption, I didn't have too many problems.
