I dunno, after talking to a few newer guys and detailed explaining on how the numpad controls work, they just don't get it.
One guy, who said he came from Minecraft, was especially confused when he clicked on the ground and only placed a ghost brick. He was even more confused when I explained him each control on the numpad, I ended up having to build a diagram to explain it. He understood after that, but other guys were just confused.
What if we could simplify building, and make the old controls optional? Maybe a click-to-build, or something just a bit simpler?
Thoughts please.
