Given it’s a game from 2004, it should be relatively easy to decompile, so if you’re the kind of person happy to tinker - it could be a great project to self-host and try to get done yourself?

That way the only cost is time, and a little bit of electricity.

I only just looked up some of the basic requirements, as it’s piqued my interest in trying to decompile something myself over the Christmas break!
