While OCaml boasts very low GC latency, I believe F# would be a better choice for writing games. It is an even more straight to the point OCaml; a Windows first class citizen; has a concurrent GC and I've heard C# is pretty popular for writing games due to Unity, so one might be able to leverage that (I don't know). A non CLOS heavy SBCL codebase would also be excellent.
