No other game offers this level of customization or creativity.
Roblox actually has a lot of freedom in terms of what you can do, yeah it uses LUA, but if we're talking about levels of customization and creativity in sandbox games in general, Roblox is definitely above Blockland
For example,
Life of an Otaku is graphically impressive considering what Roblox looks like normally, and it doesn't need third-party shader mods, so everyone can see it as it is, then there's
Purple Skittles which completely changes the game into a goofy top-down RPG where you fight via air-hockey
I got tired of Roblox, but it does amaze me to see just what kind of things people are capable of doing in that game
