I never bothered to collect anything that related to grimoire, including ghosts until I had people start kicking me because of low score... Opened up a ghost finder and collected them in a short time... I'd still be missing most if it wasn't for that. Some goes for those stupid golden chest. I didn't want ior need the [b]experience[/b] that comes along with obtains a high score. Give me my favorite weapons and I'll kill 50k enemies. Tell me to kill 10k with a weapon I don't like as much but can still be just as effective... I'll pass.
