Advertising Microsite

Hi
Lets say if i develop a simple game for a client on ios, such as just throwing ball into a basket.
Its just a mini game for advertising campaign.
Do i need to watch out for any licensing or payments?

I don’t think I understand your question - what do you mean game for an advertising campaign? It seems like you’d be doing work-for-hire, i.e. custom work for a single client. In that case the work-for-hire fees will be royalty free.

The next question is whether royalties are owed, and the answer depends on how or whether the game is monetized.

Thanks for the reply!
You are right, its work for hire.
Another question is what if i am work for hire and the project goes through the other agency
. Does the the other agency needs to pay royalties for their project which is for their client?

I don’t think I understand the question.

Sorry,
I mean lets say:

  1. I worked on an Unreal project( work for hire) at 10k and i pay royalties
  2. The project actually goes through an agency which charge its client 30k
  3. Does the agency require to pay royalties for his contracted work?

So long as it’s still custom work for a client, that all sounds like work-for-hire revenue which is royalty free.

Thanks for the answer!
