Gamedev

We made one for our previous games, but have switched to Unity for our latest. As your games grow in complexity, the developer ecosystem around more popular engines is helpful for not having to build out every piece of functionality (much of which is just redoing what others have already figured out how to do better a thousand times) from scratch. It's not a silver bullet -- we are extremely picky about the code quality and performance of any plugins we use and still create our own implementations often -- but it makes a big difference.

It sounds like OP has written their own engine to do one particular thing better than any other engine; that can be cool to see if the trade-offs in the rest of the scope aren't bad.
