Well, my build is at 10,000 bricks or so now so i've been playing a while.
Admin controls over the server are great. I can turn off vehicles and weapons and emotes and music if i wish, which for me is great. I can destroy from the ground up with the destructo wand, again, very handy. Clients bricks are safe from other players, unless trust mode is used and again i like that.
What i don't like is the fact someone can come in, save, take my build away and load it elsewhere and claim it as their own. Also, kinda linked to this is if i save, close the server and reload it later, all the other peoples bricks become mine. I end up running round making edits for people.
i think nrick ownership should save too and i don't think people should be able to save others work (apart from admins).
I'd like to congratulate Badspot right now on a damn fine retail release. Its back to the old days of proper building and good fun. Hope the moneys rolling in now BS. Don't forget the updates though ;)
I will post more concerns or bugs found as they arise. Cheers.
