I have it preordered. Will see how things play out. On the PvP thing, it sounds like there are basically two settings. Opt-in, where the enemy shoots you (for "tiny" damage), if you shoot them back then it's on. If you don't, and they still persist long enough to kill you, then they get a debuff and others will get a bonus for taking them out. Option two, disable pvp entirely. That's what I'll likely end up doing, but we'll see.

Hope the nuke launches are fun ^.^
