its very simple for me.
Bisjac is not a casual builder!
i require a hundred thousand and more bricks for massive projects, and use that to take full advantage of multiplayer fun.
when i tried roblox, it felt like lego designer. i could do small things that pretty much are meant for only me to enjoy. (due to poor multiplayer'ness of roblox and lag caused by multi players and a measly 2000 bricks.)
they keep saying the same thing; "well we have physics, makes up for the lag and low brick counts"
...no it doesn't. your "advanced physics" is just a novelty. that runs out very quickly.
