Blockland vs Wurm Online
Blockland
Blockland may be a voxel-based sandbox game in name, same as games like Minecraft, Roblox and others, but in reality, the game is a whole lot more unique due to its Lego-like features. In fact, due to its looks, many have likened the game to the unfortunately shuttered Lego Minifigures Online. Playable in single player or multiplayer, the game allows its players to unleash their creativity by creating literally anything they can think of. The game also has tons of different blocks, textures and assets (pre-made stuff) to cater to their creative needs, allowing players to come up with the most exciting mini-games and mazes as well as beautiful locations for themselves and their friends to hang out at. Players can even drive cars (sometimes vertically up the wall of a building, breaking all rules of perceived gravity in the game), ride bikes, pilot planes, and more.Although the game is no longer getting updates and apparently its community has been dwindling, Blockland is still an amazing game that answers the question of what Minecraft would look like if its "Lego-fied".

Wurm Online
Wurm Online is a unique sandbox/adventure RPG that many has been touting as being the most realistic one ever. The game is not a solo survival game unlike Minecraft. Instead, you are given the opportunity to build your own settlement - literally from the ground up - and help it to grow. Being an MMO, you can enlist the help of other players to develop your settlement from being little more than a camp with a few shabby and lopsided huts into something that passing bandits might be eyeing hungrily at.There is also an adventure element in this game where you get to venture of into the wilderness to fight a variety of creatures to earn some loot and to level up. Players who enjoy clashing swords with their fellow players can even hop into a PvP world server to enjoy some open world PvP. That said, things will go by a bit slowly if you are playing the game alone though. Wurm Online is an MMO for a reason!
The game has nothing but a fun and great experience to offer to its players and best yet, it's free to play! You can opt for a premium membership if you like just so you can play on multiple servers but, as mentioned, the game can be enjoyed without having to spend a cent.
