"No Life" - "Play multiplayer for 100 hours" - 100 Gamerpoints.
It's got some 0 Gamerpoint Achievements too, but this one caught my eye; is it a good thing or a bad thing? Good cause it makes you seem cool (I guess.. :P), or bad cause it means without it you wouldn't have a complete Achievement list (for the completionists, anyways):
"Mister NO It All" - "Negative Achievement: Skipping the Tutorial suggestion from SP". Whatever SP is.
How do you guys feel about 0 Gamerpoint Achievements, like the ones in this or DOA4? Fair game, or unneccesary?
