Regarding your question about creating a 3D game in Inventor, it's not the ideal platform for game development. Inventor is primarily a computer-aided design (CAD) software used for 3D modeling and engineering design. If you're interested in game development, you might want to explore dedicated game engines like Unity or Unreal Engine.
Now, for games like Firewatch, if you're into narrative-driven experiences with beautiful environments, you might enjoy titles such as "The Vanishing of Ethan Carter," "Gone Home," or "What Remains of Edith Finch." These games share a similar emphasis on storytelling and atmospheric exploration.
If you're looking for something specific in the realm of 3D game animation, you might want to check out the Unity Asset Store or Unreal Marketplace. These platforms often have assets and resources that can help you create or enhance your 3D game projects.
Hope this helps, and feel free to ask if you have more questions!
