Seriously BP guys, get off your high horses. I am ashamed of your actions in this topic just now.
Betrayal already stated that he's using already publicly available assets for almost everything and the few exceptions will be released along with the mod. He's perfectly entitled to do that considering the effort he (and his team where/if applicable) have put on those assets. What is important, is that the assets will be available eventually. Pressuring him to release them now should be beneath you.
Or should I remind you that the UED Solaris made by esarai was pretty much exclusive asset of BP2, as the other mod never made an actual release. Besides as you should be aware, development of mods tends to keep up right up to release of the mod. Why should he be forced to release something that may yet see much improvement between now and release of his mod?
Or do you feel like our community is so threatened by this that we can't wait for such time as to when Betrayal feels he's mod is ready enough to be released? Now think very carefully what you want to constitute here as hoarding of exclusive assets. As of now, Betrayal is an active modder working on mod(s) that at least on glance, seem to be well on their way towards finishing line. By all means suggest that he could release his exclusive assets sooner rather than later. But don't dogpile on him and most of all, don't use offensive or condescending tone when doing so. That is far bigger risk to this community than hoarding of assets.
