The chat lottery is a fun system (that we all lovingly call rigged), but it does not scale currently. With the recent steam release increasing the player count, this just makes it even less likely to win.
I'd propose each hour, pick 1 winner for every X number of active chatters to mitigate this (1/100? 1/1000? I have no point of reference for what would be balanced!)
For example, if there's 100 players chatting, 1 winner is selected that hour. If there's 200 players chatting, 2 winners are selected that hour.
This system would also have the benefit of automatically balancing the lottery during peak and off hours and further encourage chat participation.
