I'm going to clue you in on two of the most popular game engines that people use in the industry, Unity and Unreal Engine.

Unreal Engine is developed by Epic Games and Unity comes from Unity Technologies SF. Both support a wide range of operating systems, making them ideal for cross-platform development.

Epic's now aiming to tempt more Unity users over with a free five-part video tutorial series that specifically focus on helping developers and artists transition from Unity to Unreal Engine 5 ...

And Unreal 5’s monetization scheme is much more palatable for smaller developers: It’s completely free up to $1 million in revenue, with no charges based on the number of installations.
