Well in my opinion, Blockland is the best game I ever had.
Why?
In Blockland, there are tons and tons of things to do. From violent Tdms to peaceful family rps, you can make anything you want in Blockland. I mean anything.
TDMs, DMs, Jail Escapes, Slope CTFs, Speedkart, Zombie Survivals, tons of shooting games, Family rps, Medival rps, City rps, City rpgs, town rp, town rpg, community rp, community rpg, Lab rps, Scp Containment Breach, Creepypasta Rps, Escape the room, Rescue the ____, Escape the ____, Egypt rp, Beach rp, and so many more game modes to play. There's everything in this game.
In Blockland, you can do basically anything. It differs from many games because you can make anything you want. Even Minecraft rps, Gmod rps, etc.
Your friend really should get Blockland. It's an amazing game. For beginners, building can be hard, but once you get used to it, you're going to be building huge mansions and castles. Don't doubt yourself on this game, or don't doubt yourself on anything. Everyone is at a different level of building, so don't mind those who judge. It's a great game!
