Mount & Blade vs Wurm Online
Mount & Blade
Mount & Blade is the first game in a highly popular game franchise that boasts of being an RPG with one of the most sandbox-like gameplay ever. In this game, you can play as anyone you like be it a lone adventurer, a military commander or even the "mayor" of a small town in Calradia. The game also provides a rich and open world, allowing you to travel anywhere you like and discover all manner of points of interest ranging from farm villages to massive castles. You even have the freedom to interact with hundreds of characters, some of which will likely be hostile towards you. Due to this, the game provides you with an intuitive combat system that includes both sword-fighting and fighting on horseback that you can use to dispose of the hostile.Mount & Blade is an old game, and as such, its graphics may be a bit dated and its controls feel rather clunky. Thus, the game by itself might not be worth the money, but if you can get it along with Mount & Blade Warband or Mount & Blade With Fire and Sword - the two other and much better games in the series, then it'll be worth getting it.
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.
