I will share my experience with Crypto-Games.
Haven't made that much through affiliates, but I have 69 in total, not really a low number. In total I've made less than 0.01 BTC.
The stats are updated daily and you get quite a lot of info about referrals, all earnings for different coins and games. What I'd like to see though is where referrals came from, but I do not know if something like this would be possible to offer.
Referral earnings are processed (almost) instantly and I can withdraw them instantly.
I do not really understand question no 2, what do you mean by account manager?
For Slot, Blackjack and Roulette you get 25.00%, and for Dice, 25.00% of house edge on any bet made by someone you invited.
