WGTChampion: We absolutely do not make money per click/view
Unity Ads generates revenue by displaying paid advertisements in your game. The more traffic and impressions) your game creates, the more money you can earn.
Unity Ads facilitates different campaign types with different billing points (for example, completed views, clicks, or installs), and always selects the highest-earning campaign to display to your users.
The average eCPM for Unity Ads depends on many factors, such as platform, region, player demographics, and in-game placements. The biggest factor is the number of players engaging in your game.
WGTChampion: The number of credits a player makes outweighs the money that we make from the videos they watch
If that's the case, there would be no videos at all Champ. No company intentionally loses money/revenue. You used credits (player) vs money (WGT).
"The money (USD) a player makes does not outweigh the money (USD) that we make from the videos they watch" makes more sense.
I'm not directing this at you Champ. I know you're just being the messenger here and posting what you're told. So, please don't take it the wrong way.
Comparing credits to dollars isn't a fair way to put it. Consider the Amazon or iTunes Cards 165,000 credits gets a $250.00 card. Put another way, $1,650.00 (USD) buys a $250.00 (USD) gift card.
