As a way to earn credits Live Gamer has been pretty worthless for about the last 2 years or so.
First they paid off at 1 credits per view and with the extra 5 view per ad videos underneath the carousel you could make maybe 300 to 400 credits per day.
Then they changed to the payoff system we have now but with the extra 5 view vids you could still make around 150 per day,
Then the extra 5 view vids disappeared and it took slightly over 2 weeks to get 100 views to earn 75 credits. When that happened I basically stopped using Live gamer. 2 weeks to get 75 credits just wasn't how i cared to spend my time.
