If GF is advertizing other games on our forum, is it not logical they are also advertising RoM on the other games' forums. I think that is good for RoM. If you don't want to try the other games, why bother to download the clients? If you aren't downloading the clints, you shouldn't care about the link.
On the other hand, if you think DZ or any other game sounds interesting, isn't it convenient to have it right there? Seems a pretty petty issue to me.
