Mega Man X6. I don't know how many of you played this, but it was released about a month after Mega Man X5 in a rush that shows. There are bugs and glitches and poorly programmed attacks (up + saber for Zero makes him dive into a pit). It's possible to get stuck in the game and have to reset because you can't clear a large jump, and killing yourself off and continuing puts you back at the large jump you can't clear. The stages are murder, the bosses hardly attack, and the boss fortress is designed to use an armor you can't even take into the level without a conglomeration of parts that, oh yeah, you can lose forever when "rescuable reploids" die. So if you don't take that armor, you're surrounded by instant kill spikes and bosses you can only kill with their own attacks. Plus it's full of Engrish. I HATE Engrish.
