Nah not really... Considering it's just one building, and we all want to see it finished. I mean, as long as none of the material is used anywhere else, or no one uses creative mode for other things it's fine. I don't see it as cheating if everyone agrees. Besides... I feel RF is a bit of a special case considering it's actually oddworld themed.
Anyway I don't mind starting over completely... I just want to be able to take my materials with me. I spent fuckin ages collecting them x_x... But I dont mind my buildings so much. I never built much, and I can just make another Melon Slice House
I wanna make a pumpkin house as well. But damn, I think I still have 12 diamond blocks left and two stacks of iron blocks... Im not giving those up. I have plans! >: (
