I'm planning to release a free-to-play game, but i'm worried about it's monetization options. Allowing the users to purchase in-game content does not really match the game design and i didn't want to force users to do it in order to earn money from the game. Do you guys know any solution for in-game advertising? I'm planning to add:
- Ads in level loading screens, server lobby and chat rooms
- Real in-game advertising, with ads being displayed on billboards, TV's and other game areas (Webkit RTT)
