As Cobwebster has mentioned on the discord and Brandon have kind of mentioned that they will start advertising after creative is out, "because we don't wanna throw people at a network that isn't as good as it could be." ~Cob.
Anyways it shouldn't be too long for that as Cob also mentioned that they may open beta testing for Creative on the weekend.
I do like both, but I'd have to say I like burgers more.
I do like P!ATD a lot as well, I've seen them live twice, was pretty good. Also seen The Darkness live.
For xray you don't even need a client, it could just be a texture pack.
Just thought to mention that.
