Maybe not you most favorite, but a game you do enjoy. For me, in Contra 4, I can't stand the Laboratory level (stage 2). Something about it dearly annoys me, and it's not all that fun until you get to the second half of the stage going up the waterfall. Another stage would be Megaman's Iceman stage. I can't get through it, period. That game is ridiculously hard, and that's the only stage holding me back from ending it. And I can't stand Word 3 of Super Mario Bros. 3. Also known as the water stage, it's a terrible stage to me. Not that it's hard, it's nothing but water stages, which I for one hate. So, as for you all, how 'bout it?
