I have a good chuckle at some peoples HD trophy list.
There have been quite a few that I have seen that they are missing only one or two trophies for Transcendence,but they are not the usual suspects like Zone Zeus or Zico or Bling Brigade.

They have been ones like Gemini [two player split screen] or Motion Master [win a race with the motion control],Double Kill [how anybody can get all other trophies and not get this one in the process I find very strange]

The thing is,If you check their stats in a months time it would be exactly the same.
