Educational games

Q: I'm a game developer, and I had a plan to sell my game. I've read your fatwaa regarding computer games which one is halal and which one is haram. But I've still got questions about it.

My game is an Education Real Time Strategy games that teach and train user in math, physics, chemistry, ecology, and business management.

There are no music, or living things like animals, human, fantasy creature in my project. I'm trying to avoid any prohibited aspect from islamic teaching in my project.

3. Is it considered helping other in sin when i sell my products to Steam, Amazon Appstore, Google PlayStore, Apple Appstore?
