Are you my kindred spirit!? :P Thats almost exactly what I do too!
My favourite is when someone apologies for not knowing something or having dumb questions. Apart from “there is never a dumb question” because there usually isn’t, I typically respond with “if everyone already knew how to do everything, I’d be out of a job” which always seems to go down well.
We need more games that are mp co-op - just not against other people. Serious Sam on insane difficulty with a bunch of friends is damn good fun.
