This collection is getting better and better; have you thought about putting them in a pack?
It would be a bit more convenient, however, not having them in a pack lets people freely pick what they want in case they don't like one or more of the skyboxes and thus will not be stuck with skyboxes they won't be using
Also, the skyboxes aren't really related in any way other than some being from RTB 1.x and others being from requests, so it just feels weird to just toss them in a pack together
I could make an RTB Refurbished pack or something, i dunno, i'll think about it
