It was already explained a few posts above yours… And for my part, if I knew more about F#, I would ask for that, however.
But I tell you this. Rome is only as good as its people. If you think you can make games, good. But I also hope that they do sell. Nope, not just for your sake only, buy also for Epic’s sake. Because 5% of not much, is even less. And in order to make a good selling game nowadays, well, it ain’t that simple. And it gets even harder because lots of ideas are already used up. So you better don’t use tools that like to waste your time.
