I haven't gotten Ratchet, yet. I am not keen on paying over $20 for SCEA purchases when I know they're going to be $20 within a year anyway. I might get Ratchet simply because of multiplayer, but I'll probably end up getting both that and Daxter when they become Greatest Hits. Daxter has sold more copies on the PSP than anything else recently, so I'm sure its price cut is not far off.
Also, oddly enough, both Hot Shots and Wipeout Pure were from launch, so no red Greatest Hits lame-o packaging for me.
