Well I did most of Resogun trophies in co-op with a friend who care about them. I got those specific trophies because I was helping him. If it was a solo game I would not bother with them.You don't care about the platinum but you still did the very specific things that are only relevant to specific trophies, such as only using boost?
That's like the gaming equivalent of "This is just something I just threw on".
