Hey everyone, this is a re-creation of the P4P thread. The trophy requires 50 unique LBP2 plays on your level. The rules/guidelines should be pretty straight forward:
1) Search through the past week or two of posts and queue up the levels of other players using lbp.me
2) Post your PSN and a lbp.me link to your level so others can queue it.
3) Play all the levels you have queued! People who posted prior to you are much more likely to play your level after you have taken the initiative to play theirs. You can also comment on their level so they are more likely to see that you played it.
4) Continue to provide updates here and play the levels of new posters so people know you are still contributing. Make sure you return every play given to you!
EDIT: I have the platinum trophy and do not need any more plays. Thanks for your help.
