Dwarf Fortress vs Salem
Dwarf Fortress
Dwarf Fortress is one of the most unique and massive fantasy game ever made using only ASCII characters and colors. The game is completely open world in the sense that you are given the freedom to play as an adventurer and set off alone or with other adventurers on an exciting journey above or below ground (or both) to seek glory, fame and riches, or to settle down and help develop your very own dwarven outpost where you can then build a fortress, establish a barony, and in general, order your dwarven subjects around. Aside from the obviously different "art style" used, the freedom of choice, and the amazing amount of details in its gameplay, the game is also unique in its world building. The virtual world created is not only randomly generated with distinct civilizations with detailed histories, hundred of points of interests like towns and caves, as well as a flourishing nature, which includes both flora and fauna.With so many amazing features packaged into a simple-looking game, it is no wonder why Dwarf Fortress is a game that has inspired a wide variety of other modern games, both indie and big triple-A ones, until today. Due to its size, you might feel daunted to dive into a game like this, but once you've learned the basics, you will find yourself fully immersed in this completely open world of symbols and colors.
Salem
Salem is an old-school and somewhat obscure (but fun) sandbox MMORPG that unlike Wurm Online has a stronger emphasis on its in-depth crafting system and survival aspect rather than building.Similar to Wurm Online though, Salem is not a voxel-based game, but you are still able to mold the game environment through resource gathering, mining and digging in a way that reminds me of the currently-shelved MMORPG, EverQuest Next: Landmark. Of course, although not exactly the focus of the game, you can still build your homestead and the process is quite similar to Wurm Online except that it occurs at a much higher speed.
Not to mention, the game world in Salem is simply humongous to the point where it feels like an actual world. Salem also borrowed some features from ArcheAge where open-world PvP is the norm, so you'll need to be vigilant at all times, but players who kill and steal for no reason will be labelled as criminals and can be punished.
However, as good as it is despite being an indie MMO and all, Salem does have its fair share of flaws due to its low development budget. So, we'd recommend you to take a look at Salem without carrying along any high expectations. It's a pretty good MMORPG like Minecraft, but if you're expecting a Minecraft clone, you may end up disappointing yourself.
