I've played my fair share of Megaman games, and knew very well the challenge that comes with playing these games. Megaman & Bass is definitely a game that will bring forth the challenge in both its level design & bosses. The robot masters weren't all so bad, they had a good challenge for each of their level, but the King levels....those were simply just BS. If you like a good challenge that turns into torture soon after, this is the game for you (Don't play the GBA version)
