How does it work when it comes to seeing video ads to get new characters ? If for example u have only 20 characters to unlock, then would the users see the video only 20 times ? How will the game make money once it's done ? Maybe a better model would be to have some characters free, some to pay for and some with video ads ? What do u guys think ?
I have not gotten to this level but this is what I think you should do: - For each characters, assign a price tag like 100, 200, 300 etc - Watch a rewarded video to earn 20 points - To unlock character 1 with 100 point price tag, you have to watch 100/20 = 5 videos
