The physics are a great feature for Roblox, but they suck because it took around 2 minutes for a building to topple over in a server with just 3 people, where in real life it would happen in 2 seconds.
I eventually got banned on Roblox for saying 'darn you!' quite some time ago, never bothered to play it after.
Also, every other user's name was Mario.
Also x 2, it's really easy to be a friend griefer on Roblox.
