There's definitely been a lot of experimentation, but I don't think that dampened people's spirits too much, surely?
I will say that one or two games got to be so confusing that I lost interest in them, but for the most part stuff has been conventional.
I think we just had too many. The concurrents meant that people who got shafted in one game generally had a second bite, but ultimately we've come back to one off games anyway.
