lol it's actually 100,000 times harder to build things full scale. If you mess up building in miniscale, you only have to delete a few bricks to correct it. If you mess up in full scale, you may have to rebuild thousands of bricks.
been building big stuff on this game for over 6 years, i can confirm this to be true ^^^^
building at large scale is much harder than building miniature things. it takes way longer and there's far higher consequences if you screw up.
theres a lot of really good mini-empires builds out there but i can guarantee you its much harder when you're building them to fit and support full sized blockheads
