What is the difference between blockland and roblox

in block land you only have a selection of bricks every time you right click you can super jump and the only gear you get is a spay paint gun hammer and a letter launcher to fix stupid puzzles you can only play with other people if you have a code!
in roblox you have a ton of gear you can buy shirts t-shirts and pants play games with people with just an account not with a code
