I beat No More Heroes 2 a few days ago, just in time to find two used games for REALLY cheap. I found an old PS2 game called Dragon Rage for six bucks (a game on the novel concept of playing as the dragon flying around setting things on fire, destroying helpless villages and eating livestock), and also Madworld for the Wii, also six bucks. I've played them both now a bit. Madworld's a blast - if far more violent than the games I usually play, but then again, I enjoy NMH too.
Dragon Rage is fun too, though its age is show in the graphics a bit. I don't know when/if I'll settle on one or the other to complete. Or maybe I'll play them both at the same time, depending on what time of day it is. Madworld's not a game to play right before bedtime.
