We definitely view the current promotional too as good in some ways (there was much more activity and excitement in various channels for the game during that period), but we agree we need to take the opportunity to learn from what didn't work as well to provide better events in the future.
I actually had a discussion with Kaz over lunch today about how we could do something that works a bit better for an event we could do in the future. We already have a few different plans we want to try to see what players end up enjoying.
Well, Fear of the Dark Eddie is definitely much more rare to get now, but only the Haunted Pumpkins are now not obtainable. You could get really lucky one day when you least expect it...
