Lol, moderator. It's silly that BZP still has that word filtered.

I know Swert would recommend it.

It's so addicting, so I guess it depends on how much time you can afford on it, haha.

Supposedly there's an older version for free on Steam somewhere. I haven't found it but if you can find it and if it still works, you could try that as a demo of sorts.

EDIT: yup, it's called Garry's Moderator 9. There doesn't appear to be a download available though. :/
