@mattclarke, Wow, it's reflecting as here some gaming competition is going on and in my opinion these kind of contests will going to boost more gamers because their efforts are rewarded.
And in my opinion 100 Steem for sure is an effective number and hope that more gamers will going to participate and inturn gamers will be get rewarded.
And we all know that Gaming Community is #1 in this world so i hope that more and more people will going to join Steem too and that is because slowly Steem Economy is giving an opportunity to create an Gaming Dynasty.
And currently we can say that it's an Gaming Season and that is because, we can see that already Steemmonsters became the trend and there are many contests related to Steemmonsters are in place.
Wishing you an great day and stay blessed. 🙂
