i miss it
it had movers,editors wand, maybe more bricks, a lot of avatar customization(hats etc..)
i found before some days RTB 1045, blockland v0002 and BAC's pack 1.03
too bad that it doesnt work well on windows 7 and there aren't many servers
RTB devs should add gameplay features to RTB 4 like movers,bricks, not just mod mananger and irc
