Rapture Rejects Resurrection

going to have one last try for some group matches, but this time with the possibility of winning some steam keys. i'm quite a fan of getting bundles but as a result i have a significant number of extra steam keys from sites such as humble and fanatical. so in the next event if any player from the group manages to kill me after someone gets the golden ticket they get a free steam key. before i do this as an event though i'm going to need a few things.
1: a discussion on best times for people to play in both europe and american regions. i'm in the uk and i am limited to about 9am - 12 am gmt for any american events
2: a rough number of how many people would be interested in the event. if it's less than 4 for either regions not going to bother

as examples of keys you could win:
soul caliber 6
rpg maker vx ace
pillers of eternity
darkwood
red faction guerrilla
Hitman season 1
hollow knight
The Coma: Recut
Analogue: A Hate Story
skullgirls
punch club
and many more
